· Tl3AsS3

Tl3AsS3 is a thallium arsenic sulfide ceramic compound belonging to the family of ternary chalcogenides. This material is primarily of research and development interest rather than established in high-volume industrial use, investigated for its potential in optoelectronic and infrared optical applications due to its semiconducting properties and wide bandgap characteristics inherent to arsenic-sulfide systems.
