Abstract

We carried out studies to identify, synthesize, purify and grow crystals of a novel class of halides for nonlinear optical applications. Tl₃PbBr₅, Tl₄PbI₆, Tl₄HgI₆ and Tl₃PbI₅, were synthesized by reacting binary halides and crystals were grown. Optical quality was evaluated by fabricating cm size crystals. The homogeneity of bulk crystal was evaluated by studying transparency, etchpit and X-ray rocking curve and 2θ-ω scans. These halides have transparency from visible to far-IR wavelength region. The material of the compounds of Tl₃PbBr₅ composition showed self-poling during the growth.
