摘要: The color conversion glass ceramics which were made of borosilicate matrix co-doped (SrBaSm)Si2O2N2:(Eu3+Ce3+) blue-green phosphors were prepared by two-step method in co-sintering. The change in luminescence properties and the drift of chromaticity coordinates (CIE) of the (SrBaSm)Si2O2N2:(Eu3+Ce3+) blue-green phosphors and the color conversion glass ceramics were studied in the sintering temperature range from 600 ℃ to 800 ℃. The luminous intensity and internal quantum yield (QY) of the blue-green phosphors and glass ceramics decreased with the sintering temperature increasing. When the sintering temperature increased beyond 750 ℃, the phosphors and the color conversion glass ceramics almost had no peak in photoluminescence (PL) and excitation (PLE) spectra. The results showed that the blue-green phosphors had poor thermal stability at higher temperature. The lattice structure of the phosphors was destroyed by the glass matrix and the Ce3+ in the phosphors was oxidized to Ce4+, which further caused a decrease in luminescent properties of the color conversion glass ceramics.
