内容記述 | Structural and photoluminescence (PL) properties of undoped and Ce3+-doped rare-earth thiosilicate (Gd1-xCex)4(SiS4)3 (0⩽x⩽0.1) and (Y1-xCex)4(SiS4)3 (0⩽x⩽0.3) are reported. They maintain a monoclinic structure (P2_1/n) for the whole range of x. Increases in lattice constants appear with the increase in x because of the replacement of Gd3+ and Y3+ by larger Ce3+. Yellow-orange PL originating from the 5d1-4f1 (2FJ, J=5/2,7/2) transition of Ce3+ is obtained. From the measurement of PL spectra at 20 K, red shifts of the peak wavelength with the increase in x would be understood by the change of relative intensity for two luminescent centers of Ce3+ in PL bands. The maximum internal quantum efficiency is 62% for (Y_{0.85} Ce_{0.15})4(SiS4)3. These phosphors have higher water-resistance than alkaline-earth metal thiosilicate phosphors such as Ba2SiS4. | |||||
