摘要

采用高温固相法合成了CaZn

(PO

)

∶Eu

橙红色荧光粉

研究了其发光特性。该荧光粉在350~410 nm处有一个宽带激发

其激发主峰位于394 nm。在紫外激发下

发射峰分别由Eu

的

(585

595 nm)、

(615、622 nm)、

(645 nm)及

(687

700 nm)4组线状峰构成

其中以595 nm发射峰最强。探讨了Eu

的掺杂浓度对样品发光强度的影响以及Eu

发射的橙/红光比值随浓度的变化关系

确定Eu

的最佳掺杂摩尔分数为10%。实验结果表明

加入不同电荷补偿剂Li

均能使发光强度得到提高

其中以Li

最佳。

Abstract

The salmon pink phosphor CaZn

(PO

)

∶Eu

was synthesized by high temperature solid state reaction

and its luminescent characteristics were also investigated. The excitation spectra contains a broad band extending from 350 to 420 nm

which is suitable for UVLED chip

and its main peak located at 394 nm. It showed that the emission spectra of the phosphor was composed of four group major emission peaks locating at 585 and 595 nm

615 and 622 nm

654 nm

687 and 700 nm which corresponding to the

typical transition of Eu

respectively. The effects of doped-Eu

concentration to the emission intensity and the ratio of

were also investigated. It showed that the optimum doped-Eu

mole fraction is 10%. The charge compensation of Li

and K

ions to the emission intensity was also studied

and it found that Li

ions gave the best improvement to enhance the intensity of the emission.
