'''Lead(II) iodide''' (or '''lead iodide''') is a chemical compound with the formula {{chem|Pb|I|2}}. At [[room temperature]], it is a bright yellow odorless [[crystal]]line solid, that becomes orange and red when heated.<ref name="sigma" /> It was formerly called '''plumbous iodide'''.

The compound currently has a few specialized applications, such as the manufacture of [[solar cells]],<ref name=Dhiaputra/> [[X-ray]]s and [[gamma rays|gamma-ray]] detectors.<ref name=Shah/> Its preparation is an entertaining and popular demonstration in [[chemistry]] education, to teach topics such as [[precipitation reaction]]s and [[stoichiometry]].<ref name="anthony" /> It is [[photolysis|decomposed by light]] at temperatures above {{convert|125|C|F}}, and this effect has been used in a patented [[photography|photographic]] process.<ref name="patnaik" /><ref name="patphot" />

Lead iodide was formerly employed as a yellow pigment in some paints, with the name '''iodide yellow'''. However, that use has been largely discontinued due to its toxicity and poor stability.<ref name=Eastaugh/>

== Preparation ==

{{chem|Pb|I|2}} is commonly synthesized via a precipitation reaction between [[potassium iodide]] {{chem|K|I}} and [[lead(II) nitrate]] {{chem|Pb}}({{chem|N|O|3}})<sub>2</sub> in water solution:

: {{chem2|Pb(NO3)2 + 2 KI → PbI2 + 2 KNO3}}

While the potassium nitrate {{chem|K|N|O|3}} is soluble, the lead iodide {{chem|Pb|I|2}} is nearly insoluble at [[room temperature]], and thus [[precipitate]]s out.<ref name=Ahmad/>

Other soluble compounds containing lead(II) and iodide can be used instead, for example [[lead(II) acetate]]<ref name=Dhiaputra/> and [[sodium iodide]].

The compound can also be synthesized by reacting [[iodine]] vapor with molten [[lead]] between 500 and 700&nbsp;°C.<ref name="matuz" />

A thin film of {{chem|Pb|I|2}} can also be prepared by depositing a film of [[lead(II) sulfide|lead sulfide]] {{chem|Pb|S}} and exposing it to iodine vapor, by the reaction

: {{chem2|PbS + I2 → PbI2 + S}}

The [[sulfur]] is then washed with [[dimethyl sulfoxide]].<ref name="chaud" />

== Crystallization ==

Lead iodide prepared from cold solutions usually consists of many small hexagonal platelets, giving the yellow precipitate a silky appearance. Larger crystals can be obtained by exploiting the fact that [[solubility]] of lead iodide in water (like those of [[lead(II) chloride|lead chloride]] and [[lead(II) bromide|lead bromide]]) increases dramatically with temperature. The compound is colorless when dissolved in hot water, but crystallizes on cooling as thin but visibly larger bright yellow flakes, that settle slowly through the liquid — a visual effect often described as "golden rain".<ref name="gold" /> Larger crystals can be obtained by [[autoclave|autoclaving]] the {{chem|Pb|I|2}} with water under pressure at 200&nbsp;°C.<ref name="zhu"/>

Even larger crystals can be obtained by slowing down the common reaction. A simple setup is to submerge two [[Beaker (glassware)|beaker]]s containing the concentrated reactants in a larger container of water, taking care to avoid currents. As the two substances [[diffusion|diffuse]] through the water and meet, they slowly react and deposit the iodide in the space between the beakers.<ref name="tub" />

Another similar method is to react the two substances in a [[gel]] medium, that slows down the diffusion and supports the growing crystal away from the container's walls. Patel and Rao have used this method to grow crystals up to 30&nbsp;mm in diameter and 2&nbsp;mm thick.<ref name="patrao" />

The reaction can be slowed also by separating the two reagents with a permeable membrane. This approach, with a [[cellulose]] membrane, was used in September 1988 to study the growth of {{chem|Pb|I|2}} crystals in zero gravity, in an experiment flown on the [[Space Shuttle Discovery]].<ref name=Scaife/>

{{chem|Pb|I|2}} can also be crystallized from powder by [[Sublimation (phase transition)|sublimation]] at 390&nbsp;°C, in near [[vacuum]]<ref name="forn" /> or in a current of [[argon]] with some [[hydrogen]].<ref name=Liu/>

Large high-purity crystals can be obtained by [[zone melting]] or by the [[Bridgman–Stockbarger technique]].<ref name="matuz" /><ref name="forn" /> These processes can remove various impurities from commercial {{chem|Pb|I|2}}.<ref name=Tonn/>

== Applications ==

Lead iodide is a precursor material in the fabrication of highly efficient [[Perovskite solar cell]]. Typically, a solution of {{chem|Pb|I|2}} in an organic solvent, such as [[dimethylformamide]] or dimethylsulfoxide, is applied over a [[titanium dioxide]] layer by [[spin coating]]. The layer is then treated with a solution of [[methylammonium iodide]] {{chem|C|H|3|N|H|3|I}} and [[Annealing (metallurgy)|annealed]], turning it into the [[double salt]] [[methylammonium lead iodide]] {{chem|C|H|3|N|H|3|Pb|I|3}}, with a [[perovskite]] structure. The reaction changes the film's color from yellow to light brown.<ref name=Dhiaputra/>

{{chem|Pb|I|2}} is also used as a high-energy photon detector for gamma-rays and X-rays, due to its wide band gap which ensures low noise operation.<ref name="patnaik" /><ref name=Shah/><ref name="forn" />

Lead iodide was formerly used as a paint pigment under the name "iodine yellow". It was described by [[Prosper Mérimée]] (1830) as "not yet much known in commerce, is as bright as [[orpiment]] or [[lead(II) chromate|chromate of lead]]. It is thought to be more permanent; but time only can prove its pretension to so essential a quality. It is prepared by precipitating a solution of acetate or nitrate of lead, with potassium iodide: the nitrate produces a more brilliant yellow color."<ref name=Eastaugh/> However, due to the toxicity and instability of the compound it is no longer used as such.<ref name=Eastaugh/> It may still be used in art for [[bronzing]] and in gold-like [[mosaic]] tiles.<ref name="patnaik" />

== Stability ==
Common [[Characterization (materials science)|material characterization]] techniques such as [[Electron microscope|electron microscopy]] can damage samples of lead(II) iodide.<ref>{{Cite journal |last=Forty |first=A. J. |date=August 1960 |title=Observations of the decomposition of crystals of lead iodide in the electron microscope |journal=Philosophical Magazine |volume=5 |issue=56 |pages=787–797 |bibcode=1960PMag....5..787F |doi=10.1080/14786436008241217}}</ref> [[Thin film]]s of lead(II) iodide are unstable in ambient air.<ref>{{Cite journal |last1=Popov |first1=Georgi |last2=Mattinen |first2=Miika |last3=Hatanpää |first3=Timo |last4=Vehkamäki |first4=Marko |last5=Kemell |first5=Marianna |last6=Mizohata |first6=Kenichiro |last7=Räisänen |first7=Jyrki |last8=Ritala |first8=Mikko |last9=Leskelä |first9=Markku |date=2019-02-12 |title=Atomic Layer Deposition of PbI<sub>2</sub> Thin Films |journal=Chemistry of Materials |volume=31 |issue=3 |pages=1101–1109 |doi=10.1021/acs.chemmater.8b04969 |doi-access=free}}</ref> Ambient air oxygen oxidizes iodide into elemental [[iodine]]:

: {{chem2|2 PbI2 + O2 → 2 PbO + 2 I2↑}}

== Toxicity ==

Lead iodide is very toxic to human health. Ingestion will cause many acute and chronic consequences characteristic of [[lead poisoning]].<ref name=Flora/> Lead iodide has been found to be a carcinogen in animals suggesting the same may hold true in humans.<ref>{{Cite web |title=Haz-Map Category Details |url=https://hazmap.nlm.nih.gov/category-details?id=2524 |access-date=2016-04-29 |website=hazmap.nlm.nih.gov}}</ref> Lead iodide is an inhalation hazard, and appropriate respirators should be used when handling powders of lead iodide.

== Structure ==

The structure of {{chem|Pb|I|2}}, as determined by [[X-ray powder diffraction]], is primarily hexagonal close-packed system with alternating between layers of lead atoms and iodide atoms, with largely ionic bonding. Weak van der Waals interactions have been observed between lead–iodide layers.<ref name=Shah/> The most common stacking forms are 2H and 4H. The 4H polymorph is most common in samples grown from the melt, by precipitation, or by sublimation, whereas the 2H polymorph is usually formed by [[sol-gel]] synthesis.<ref name=str/> The solid can also take an R6 rhombohedral structure.<ref>{{Cite journal |last1=Sears |first1=W.
