摘要

采用碳包埋方法制备了不同Eu

掺杂浓度的七铝酸十二钙（C12A7:

% Eu

）导电荧光粉。在254 nm的紫外光激发下，样品呈现出位于444 nm的蓝光宽带发射峰，其来源于Eu

的4f

-4f

跃迁。当Eu

的掺杂浓度为1.0%时，蓝光发射强度最大。通过漫反射吸收光谱结合经验公式可计算C12A7:1.0% Eu

粉末样品的困陷于笼中的电子浓度为3.4010

-3

。在空气气氛下对C12A7:1.0% Eu

样品进行热处理，通过减少困陷于笼中的电子浓度，即增加困陷于笼中的O

离子浓度，可进一步提高样品的发光强度。阴极射线发光实验结果表明:铕掺杂七铝酸十二钙蓝光发射导电荧光粉在低压场发射显示器件中有潜在的应用前景。

Abstract

doped 12CaO7Al

(C12A7:

% Eu

) conductive phosphors with different concentrations were synthesized by a melting solidification method. Upon 254 nm UV excitation

we can observe a broad blue emitting band peaked at 444 nm

which originates from the 4f

-4f

transition of Eu

. As the Eu

doping concentration is 1.0%

the strongest emission intensity can be achieved. The conductive performance of Eu

doped 12CaO7Al

phosphors can be attributed to the generation of encaged electrons and the calculated encaged electron concentration is~3.4010

-3

. After the conductive phosphor was annealed in air

its photoluminescence intensity increased with increasing the amount of encaged O

anions (

i.e

. decreasing the amount of encaged electrons). Our results suggest that C12A7:Eu

blue emitting conductive phosphors have a potential application in field emission displays.
