摘要

激活的铝酸锂是深红色发射的红色荧光粉

其发射的峰值波长为675 nm

呈现出少有的纯正的深红色发光。本文对LiAl

Abstract

Iron-activated LiAl

is one of red emitting phosphors

exhibiting a broad-band photoluminescence peaked around 675 nm. The component of the matrix and the content of activation ion in LiAl

∶ Fe

phosphors were studied in this paper. The results shown that

under the monitoring at 673 nm

the ordered phase of excitation spectra indicated that there is a strong absorption band at 284 nm

which is charge transfer band of Fe

-O

.And there is a single emission band at 673 nm emission under 254 nm excitation. And the emission band is slight asymmetry in the direction of longer wavelength

which belongs to

(

S) transition.The luminescent intensity is the strongest when the content ratio of Li

and Al

is 0.21. The emission intensity enhances as the content of Fe

increases. When the content of Fe

is 0.5%

the luminescent intensity is the strongest. But the luminescent intensity decreases when the content of Fe

increases over 0.5%.
