摘要

BaMgAl

: Eu

(BAM)是三基色荧光灯和等离子显示用荧光粉中的蓝色组分。用晶格弛豫和多声子跃迁理论研究了BAM发射光谱的谱峰分布。结果表明可以用三个高斯函数很好地拟合BAM的宽带发射。BAM的宽带发射可能由分布在BaMgAl

晶格中三个不同位置的Eu

的能级跃迁构成。三个Eu的发光中心分别是Beevers-Ross位和anti-Beevers-Ross 位

第三个Eu

的发光中心可能是位于尖晶石基块中的mid-oxygen(m

)位。

Abstract

BaMgAl

: Eu

(BAM) is the blue phosphor component of three-color fluorescent lamps and plasma display panels(PDP).In present paper the emission spectra lineshape of BAM were investigated by using lattice relation and theory of multiphonon transitions.The result indicated that the broadening emission band of BAM can be fitted by three Gaussian functions very well

the transitions from three different site of Eu

in the BAM lattice forms the BAM emission spectra

the two of the emission centers are assigned to Eu

at normal Beevers-Ross sites and anti-Beevers-Ross sites

respectively

but the third luminescence center may be located at mid-oxygen (m

)sites.
