中文摘要：

采用高温熔融法制备了一系列Ce^3＋／Sm^3＋共掺透明微晶玻璃，并研究了其发光特性。在微晶玻璃中Ce^3＋呈现出基于4f-5d跃迁的较强的宽带蓝光发射，通过调节Ce^3＋／Sm^3＋离：子的掺杂浓度，Ce^3＋／Sm^3＋离子共掺微晶玻璃发光的色度逐渐发生变化，当Ce^3＋／Sm^3＋掺杂的量比为1：1时，制得的微晶玻璃发光色坐标为（0．315，0．296）。通过光谱和荧光：衰减曲线，研究了Ce^3＋离子到Sm^3＋离子的能量传递，在SAZKNGC0.6S0.6。微晶玻璃中，Ce^3＋离子向Sm^3＋离子传递能量效率约为20％。结果表明，Ce^3＋／Sm^3＋共掺微晶玻璃是白光LED的一种潜在基质材料。

英文摘要：

A series of transparent Ce^3＋/Sm^3＋ co-doped glass ceramics were prepared by high temperature melting, and their luminescence properties were studied. In the glass ceramics, Ce^3 ＋ ions have shown efficient broadband blue emission due to the 4f-5d transition, and Sm^3＋ ions have shown bright orange-red luminescence resulting from the ^4G5/2→^6Hj （J = 5/2,7/2,9/2,11/2） transitions. By adjusting the doped concentration of Ce^3＋ and Sm^3 ＋ ions, the chroma of the samples varied gradually. When the mole fraction of CeO2 and Sm2 03 was 1 ： 1, the white light lumines- cence glass ceramic with the chromaticity coordinate （0.315,0. 296） was prepared. The energy transfer from Ce^3＋ to Sm^3＋ ions were investigated by spectra properties and fluorescence decay curves, energy transfer efficiency is about 20% in the SAZKNGC0.6S0.6 glass ceramics. The results indicate that Ce^3＋/Sm^3- co-doped glass ceramics containing β-Zn2SiO4 are potential matrix materials for white LEDs.
