· JVASP-105362· TlIn2GaSe4

TlIn2GaSe4 is a ternary chalcogenide ceramic compound belonging to the III-V semiconductor family, combining thallium, indium, gallium, and selenium. This material is primarily of research and developmental interest for infrared optics and nonlinear optical applications, where its wide bandgap and selenium-based composition make it a candidate for mid-infrared transmission windows and frequency conversion devices. While not yet widely deployed in mainstream industrial applications, compounds in this family are investigated as alternatives to more conventional IR materials where thermal stability, transmission range, or nonlinear coefficients offer advantages over established options.
