摘要

采用高温固相法合成了白光LED用蓝绿色荧光材料BaSi

:Eu

。用X射线衍射(XRD)、光致发光(PL)等对荧光材料进行了表征。XRD结果表明

所制备的样品为较好的单相。BaSi

:Eu

在395 nm和460 nm激发下均具有较高的发射强度

发射峰位于492 nm附近。当Eu

的摩尔分数为4%时

可以获得最佳的样品发光强度。将荧光材料封装在紫外和蓝光芯片上制作了LED器件

两种器件均发射出强的蓝绿色荧光

色坐标分别为(0.092 0

0.428 2)和(0.112 9

0.223 0)。

Abstract

The oxonitride blue-green phosphor BaSi

∶Eu

has been prepared by solid state reaction. The prepared BaSi

∶Eu

phosphors are characterized by X-ray powder diffraction (XRD)

photoluminescence (PL)

etc.

The XRD results show that pure phase phosphors are obtained. The PL results demonstrate that BaSi

∶Eu

shows high efficient emission with peak at around 492 nm. The best emission can be obtained with the Eu

mole fraction of 4%. The phosphors are encapsulated on the ultraviolet and blue chips

high blue-green luminescence is obtained in both devices

and the CIE parameters are (0.092 0

0.428 2) and (0.112 9

0.223 0)

respectively.
