英文摘要	A series of ce3+-activated k4srsi3o9 materials emitting bright blue light under near-uv excitation was obtained by a facile solid-state reaction. the luminescence of ce3+-doped k4srsi3o9 shows excellent thermal stability in a large temperature range. the detailed temperature/concentration-dependent luminescent properties of ce3+ confirm that there are two different ce3+ sites in k4srsi3o9: ce3+, and energy transfer from the high-energy ce(1)(3+) sites to the low-energy ce(2)(3+) sites was demonstrated to occur by electric dipole-dipole interaction. the maximum photoluminescence quantum yield of ce3+-doped k4srsi3o9 can reach 56%, and a uv-excited white led device with low correlated color temperature (cct= 4617 k) and high color-rendering index (r-a= 80) was fabricated with k4srsi3o9:ce3+.
