摘要

采用高温固相法

合成了三价稀土离子(

=Ce

)掺杂的Na

CaSiO

(NCS)系列样品

并研究了其在紫外光激发下的发光特性。研究结果表明

、Tb

和Eu

掺杂的NSC系列样品在紫外光源激发下

均呈现其特征发射

随着掺杂浓度的提高

发射强度逐渐增大。Ce

、Tb

和Eu

的最佳摩尔分数分别为0.13、0.13和0.12

相应的色坐标分别计算为(0.17

0.17)、(0.34

0.58)和(0.66

0.34)

分别为很好的蓝光、绿光和红光。继续增加稀土离子的含量

发射强度降低。

Abstract

CaSiO

∶

(

=Ce

) (NCS) samples were synthesized by high temperature solid-state reaction and their luminescence characteristics were investigated. The photoluminescence (PL) spectra of Ce

and Eu

doped NSC samples show characteristic intra-configurational 4f-5d transitions of Ce

4f-4f transitions of Tb

and 4f-4f transitions of Eu

under ultraviolet excitation. The emission intensity increases with the concentration of

and then decreases when doping concentration over a certain value. The concentration quenching value of Ce

and Eu

are 0.13

0.13 and 0.12

respectively. The Commission Internationale de l'Eclairage (CIE) chromaticity coordinates of Ce

and Eu

doped NSC samples are (0.17

0.17)

(0.34

0.58) and (0.66

0.34)

respectively.
