· JVASP-12540· K2ZnBr4

K2ZnBr4 is an inorganic halide ceramic compound combining potassium, zinc, and bromine elements, belonging to the family of metal halide ceramics. This material is primarily of research interest for optical and optoelectronic applications, where halide compounds are investigated for scintillation detection, radiation sensing, and potential photonic devices due to their transparency and electronic properties. As a specialized compound, K2ZnBr4 represents the broader class of zinc halides being explored in advanced detector systems and photonic applications where conventional oxide ceramics are inadequate.
