摘要

采用高温熔融法制备了Ce

/Tb

/Sm

掺杂的CaO-B

-SiO

（CBS）发光玻璃。通过傅利叶红外光谱仪、荧光光谱仪表征了该系列发光玻璃的微观结构和发光性质，并对Ce

到Tb

、Ce

到Sm

之间的能量传递机制进行了研究。结果表明，在339，378，407 nm激发下，单掺Ce

、Tb

和Sm

的CBS玻璃分别发射紫蓝光、绿光和红光，恰好符合混合合成白光的条件。Ce

/Tb

和Ce

/Sm

双掺CBS玻璃的发射光谱以及Ce

衰减寿命的变化证实了Ce

和Ce

之间存在能量传递，随Tb

和Sm

浓度增加，Ce

的寿命减小，且传递效率由5.4%和5.7%分别增加至24.0%和27.1%。调节3种稀土离子的掺杂浓度并选择合适的激发波长，实现了发光颜色可调，并最终获得白光发射。

Abstract

A series of Ce

/Tb

/Sm

doped CaO-B

-SiO

(CBS) luminescent glasses were prepared by melting method at high temperature. The microstructure and luminescentce properties of CBS glasses were characterized with Fourier infrared spectrometer and photoluminescence spectrometer. Purplish blue

green

and red emission bands were observed in the emission spectra of Ce

/Tb

/Sm

single-doped CBS glasses excited by 339

378

407 nm

respectively. These emission bands just meet the requirements of hybrid synthetic white light. The emission spectra and decay curves of Ce

/Tb

and Ce

/Sm

co-doped CBS glasses have proved the existence of energy transfer. The average life time of Ce

decreases with the increasing Tb

or Sm

concentration. At the same time

the energy transfer efficiency increases from 5.4% and 5.7% to 24.0% and 27.1%

respectively. CIE color coordinates of Ce

/Tb

/Sm

co-doped CBS glasses shift from cyan to white with increased excitation wavelength. A complex white light emitting is obtained when Ce

/Tb

/Sm

concentration equals 0.375%/4%/1.5%

respectively.
