Abstract:

The objective of this program was to determine the phase equilibria in the systems Tl-As-S and Tl-As-Se and a portion of the quaternary system Tl- As-S-Se so as to optimize crystal growth of compounds in these systems, notably Tl2AsS3, Tl3AsSe3, and Tl3AsS4. These compounds form promising nonlinear optical and acousto-optical crystals. Optical techniques were to be used to evaluate crystal quality and the optical properties of any new compounds encountered were to be investigated to determine their potential as useful optical materials.
