Ce³⁺-activated single phase β-Ca₂Si(O,N)₄ (CSON) and α′-Sr₂Si(O,N)₄ (SSON) oxonitridosilicate phosphors were synthesized by a conventional solid state reaction method at 1100 °C using LiF as a flux. For comparative purposes, their oxide equivalents, β-Ca₂SiO₄ (CSO) and α′-Sr₂SiO₄ (SSO), doped with Ce³⁺ were obtained using the same synthesis method. The incorporation of nitrogen in the phosphors was confirmed by Energy Dispersive Spectroscopy (EDS). The formation of Sr-N and Si-N bonds can be observed in the FT-IR spectra. The oxide phosphors showed single intense broad band of Ce³⁺ emissions centered at 415 (CSO:Ce³⁺) and 425 nm (SSO: Ce³⁺) after ultraviolet irradiation. The oxonitridosilicate phosphors exhibited two-band emissions from Ce³⁺ occupying two Ca²⁺ or Sr²⁺ sites. The emissions were red shifted compared to their oxide counterparts, blue-green for CSON:Ce³⁺ and green for SSON:Ce³⁺. The thermal stability and quantum yields (QY) of oxonitridosilicate phosphors were significantly improved compared with respective oxide phosphors. Exceptional thermal stability of SSON:Ce³⁺ phosphor (90% of initial emission intensity at 200 °C) and high QY (85%) means that this phosphor can be used in white light emitting diodes.
