· JVASP-58880· Tl6SBr4

Tl6SBr4 is a mixed-halide thallium sulfide bromide ceramic compound belonging to the family of heavy-metal chalcohalides. This material is primarily a research and experimental compound studied for its potential in infrared optical and photonic applications, as the thallium and halide components can exhibit useful optical transmission windows in the mid-to-far infrared spectrum. While not yet widely deployed in mainstream industry, such chalcohalide ceramics are of interest to the optoelectronics and sensing communities as candidates for infrared optics, nonlinear optical devices, and specialized detector materials where conventional materials reach their wavelength limits.
