摘要

以Eu

(AR)、Sr(NO

)

(AR)、Mg(NO

)

O(AR)、Al(NO

)

O(AR)为原料

HCO

为沉淀剂

采用化学共沉淀法制备前驱物

经一次煅烧制备出蓝色荧光粉SrMgAl

:Eu

。用X射线衍射仪、荧光分光光度计分别测试样品结构与发光性能。结果表明:在1 200℃下煅烧即可生成六方结构的SrMgAl

:Eu

比高温固相法煅烧温度低300℃;其发射光谱最强峰在470 nm

的最佳掺杂摩尔分数为10%;选用H

为助熔剂

可提高粉体发光强度

其最佳质量分数为1.5%。

Abstract

SrMgAl

:Eu

blue phosphor was obtained by one-step calcination process of precursor synthesized by the co-precipitation method. Eu

(AR)

Sr(NO

)

(AR)

Mg(NO

)

O(AR)

Al(NO

)

O(AR) were used as raw materials and NH

HCO

was as precipitating agent. The crystal structure and luminescent properties of the samples were analyzed by the X-ray diffraction and the fluorescence spectrophotometer. The results show that the calcination temperature can be dropped to 1 200℃

which is 300℃ lower than the temperature of high temperature solid state reaction. The peak of emission wavelength of SrMgAl

:Eu

is at 470 nm. The optimum mole fraction of Eu

is 10%. H

was chosen as fluxes agent

and the optimum mass fraction is 1.5%.
