· JVASP-116726· La2MgSe4

La2MgSe4 is a ternary ceramic compound composed of lanthanum, magnesium, and selenium, belonging to the class of mixed-metal selenides. This material is primarily investigated in research contexts for optoelectronic and solid-state applications, particularly where wide bandgap semiconductors or ionic conductors are needed. Its potential applications leverage the favorable electronic properties of rare-earth selenides combined with magnesium's role in stabilizing crystal structure, making it of interest for next-generation thermoelectric devices, solid electrolytes, and photonic components where conventional oxides or sulfides may be limiting.
