摘要

以Eu

、NH

、BaCl

O、BaCO

为原料，用高温固相法制备出Ba

（PO

）

Cl：Eu

荧光粉。用XRD衍射仪和荧光分光光度计分别测试样品的物相结构和荧光性能。结果表明：制备得到的Ba

（PO

）

Cl：Eu

为单相，在245~425 nm范围均有较大吸收，具有最强峰在435 nm的窄带发射。该荧光粉的发光强度受Eu

浓度的影响较大，其发光随着Eu

浓度的增加先增强后减弱。当Eu

摩尔分数为3%时，发光强度达到最大。

Abstract

(PO

)

Cl:Eu

phosphors were synthesized by a high temperature solid state reaction with Eu

BaCl

and BaCO

as the raw materials. The crystal structure and luminescent properties of the samples were analyzed by the X-ray diffraction and the fluorescence spectrophotometer. The results show that Ba

(PO

)

Cl:Eu

phosphors synthesized are pure

the excitation spectrum contains a broad band in a range of 245~425 nm

and the emission band locats in 400~500 nm

indicating Ba

(PO

)

Cl:Eu

is a blue phosphor under near UV excitation. Eu

concentration affects the luminescent intensity of Ba

(PO

)

Cl:Eu

phosphor synthesized seriously. The emission intensity firstly increases and then decreases as Eu

content increases. The emission intensity reaches the maximum when the doped Eu

concentration is 3%.
