| 摘 要： | 采用高温熔融法制备了Sm3+/Ce3+/Tb3+共掺杂的CaO-B2O3-SiO2发光玻璃材料,并用荧光分光光度计和CIE色度坐标对其发光性能进行了研究。发射光谱表明,在374nm激发下,Sm3+/Ce3+/Tb3+共掺杂CaO-B2O3-SiO2发光玻璃的发射光谱中同时观测到了红橙光、蓝光和绿光的发射带,这些发射带的混合实现了白光发射。此外,在Sm2O3和Tb4O7含量不变的情况下,随着CeO2含量的减小,Sm3+/Ce3+/Tb3+共掺杂发光玻璃的发光颜色在白光区逐渐由蓝光区附近过渡到黄光区附近。

| Abstract: | The luminescent CaO-B2O3-SiO2 glasses codoped with Sm3+/Ce3+/Tb3+ have been synthesized by high temperature melting method and the luminescence properties of the samples were investigated by photoluminescence(PL) spectra and CIE chromaticity coordinate.Reddish orange,blue and green emission bands were observed in the emission spectra of Sm3+/Ce3+/Tb3+ codoped glasses.The combination of these emission bands allows the realization of white light when the glasses are excited by near ultraviolet light.In addition,with the decreasing of the CeO2,the white emission gradually shifted from blue to yellow can be observed in the emission spectra of luminescent glasses with a certain content of Sm2O3 and Tb4O7. |
