· JVASP-3249· Nd2SeO2

Nd2SeO2 is a rare-earth selenide oxide ceramic compound combining neodymium with selenium and oxygen, belonging to the family of lanthanide oxyselenides. This material is primarily of research interest rather than established commercial production, explored for its potential in optical, electronic, and thermal applications where rare-earth compounds offer unique electromagnetic properties. The material's significance lies in investigating how rare-earth dopants and selenide chemistry can be engineered for specialized ceramics in optoelectronics, photonics, and high-temperature applications where conventional oxides reach performance limits.
