ChemInform Abstract: Narrow‐Band Green‐Emitting Phosphor Ba₂LiSi₇AlN₁₂:Eu²⁺ with High Thermal Stability Discovered by a Single Particle Diagnosis Approach.

Abstract

Luminescent particles of Ba2LiSi7AlN12:Eu2+ are selected from polycrystalline material obtained by firing Ba3N2, EuN, Si3N4, AlN, and Li3N under N2 in the molar ratio of Eu:Si:Al:Li = 0.8:0.2:0.58:6.42:3 (BN crucible, 1800 °C, 2 h, 1 MPa N2).
