摘要

采用高温固相法合成Sr

，Li

红色荧光粉，考察了激活剂Eu

和电荷补偿剂Li

浓度对Sr

：Eu

，Li

荧光粉发光性能的影响。结果表明：适量掺杂Eu

、Li

离子并不改变Sr

的结构。当Eu

掺杂量为4%、Li

的掺杂量为8%时，在900 ℃下灼烧2 h可以得到发光性能最佳的Sr

2.9

：0.04Eu

，0.08Li

红色荧光粉。以394 nm的近紫外光激发时，Sr

：Eu

，Li

荧光粉发射出红光，对应于Eu

的4f-4f 跃迁，其中以614 nm附近的

跃迁发光最强，是一种有潜力用于白光LED的红色荧光粉。

Abstract

The red phosphor Sr

:Eu

was prepared by high temperature solid-state method. The effects of the concentration of activating agent Eu

and sensitizing agent Li

on luminescent properties of Sr

:Eu

were investigated. The results show that there is not obvious structure transformation of Sr

after appropriate amounts of Eu

and Li

doping. The optimal doping content of Eu

and Li

are 4% and 8%

respectively. The optimal temperature is 900 ℃ for 2 h. The phosphor Sr

:Eu

can be excited by 394 nm near-UV light and emits red light corresponding to the 4f-4f transition of Eu

. Its strongest emission peak is attributed to the

transition of Eu

at about 614 nm. The phosphor could be a promising red phosphor for white LED.
