· JVASP-145233· La3AlZnS7

La3AlZnS7 is a rare-earth metal sulfide compound combining lanthanum, aluminum, and zinc in a ternary sulfide system. This is a research-phase material studied primarily for its optical and electronic properties rather than a commercial engineering alloy; compounds in this family are being investigated for potential applications in solid-state lighting, photocatalysis, and semiconductor technologies where rare-earth sulfides offer tunable band gaps and luminescent behavior.
