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

双掺CBS玻璃的发射光谱以及Ce

(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
3+
/Tb
3+
/Sm
3+
single-doped CBS glasses excited by 339

respectively. These emission bands just meet the requirements of hybrid synthetic white light. The emission spectra and decay curves of Ce
3+
/Tb
3+
and Ce
3+
/Sm
3
co-doped CBS glasses have proved the existence of energy transfer. The average life time of Ce
3+
decreases with the increasing Tb
3+
or Sm
3+
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
3+
/Tb
3+
/Sm
3+
co-doped CBS glasses shift from cyan to white with increased excitation wavelength. A complex white light emitting is obtained when Ce

/Tb

/Sm
3+
concentration equals 0.375%/4%/1.5%
respectively.
