· JVASP-35261· Na2Zn2Se3

Na2Zn2Se3 is an inorganic ceramic compound belonging to the ternary selenide family, combining sodium, zinc, and selenium elements into a crystalline structure. This material is primarily of research interest for optoelectronic and photovoltaic applications, where its semiconducting properties and band structure are being explored for potential use in solar cells, photodetectors, and other light-responsive devices. Compared to more mature alternatives like CdTe or CdSe quantum dots, selenide compounds like Na2Zn2Se3 offer the advantage of lower toxicity and tunable electronic properties through compositional variation, making them promising candidates for next-generation thin-film photovoltaics and sensing technologies.
