Thallium halides
These salts find use in specialized optical settings, such as focusing elements in research spectrophotometers.Compared to the more common zinc selenide-based optics, materials such as thallium bromoiodide enable transmission at longer wavelengths.The materials were first grown by R. Koops in the laboratory of Olexander Smakula at the Carl Zeiss Optical Works, Jena in 1941.KRS-5 is the most commonly used, its properties of being relatively insoluble in water and non-hygroscopic, make it an alternative to KBr, CsI, and AgCl.[8] The thallium trihalides, also known as thallic halides, are less stable than their corresponding aluminium, gallium, and indium counterparts and chemically quite distinct.
