Effect of BaCl2 flux on low temperature synthesis of Ba3Si6O12N2:Eu phosphors from BaCN2 and SiO2

Abstract
Green Ba3Si6O12N2:Eu and Ba3Si6O9N4:Eu phosphors were synthesized below 1000 °C using Eu-doped BaCN2 as a nitrogen and barium source in conjunction with SiO2. The development of low-temperature synthesis methods is necessary to reduce energy consumption during the solid-state syntheses of inorganic materials. However, low-temperature reactions tend to provide oxynitride phosphors showing poor crystallinity and low photoluminescence (PL) intensity. In this study, the effect of a BaCl2 flux on the low-temperature synthesis of Ba3Si6O12N2:Eu phosphors from BaCN2 and SiO2 was investigated. The crystallinity and phase purity of the Ba3Si6O12N2:Eu phosphors increased with increasing amount of BaCl2 employed. The maximum PL intensity obtained from an oxynitride phosphor prepared with a BaCl2 flux was almost twice that of material prepared without BaCl2.
