Triatomic Centrosymmetric Crystals

Abstract

A large number of sulfosalt compounds was investigated to determine the usefulness of such materials as infrared window materials, particularly at 10.6 micrometers. Polycrystalline synthesis were followed in a few instances by crystal-growth experiments and determination of absorption coefficients. Of the many materials examined, TlInS2, TlGaSe2, and TlAsSe3 show most promise as window materials; in fact, the best measured absorption coefficient for Fl3AsSe3 (0.016/cm) is the lowest ever measured on a material of this type. Particularly for Tl3AsSe3, it propagation through the crystal.
