Paper 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.
