· JVASP-37167· NaHoSe2

NaHoSe₂ is a rare-earth ceramic compound combining sodium, holmium, and selenium in a layered crystal structure. This is a research-phase material studied primarily in solid-state chemistry and materials science contexts for its potential electrochemical and photonic properties. While not yet commercialized at scale, sodium rare-earth chalcogenides like NaHoSe₂ are being investigated for energy storage applications, optical devices, and as model systems for understanding ion transport in ceramic electrolytes.
