Abstract

The red emitting phosphors

AlO

(

=Ca

=La

Gd) were synthesized through the solid state reaction technique. The photoluminescence properties were described. Upon excitation with UV and near UV light excitation

the photoluminescence emission spectra could be assigned to the transitions of Eu

from the initial state

to the final states

(J=

4). The two strong emissions peaked at 590 nm and 620 nm

which arose from the

and

transitions of Eu

respectively. The photoluminescence excitation spectra show abroad O

-Eu

charge-transfer band and f-f transitions. O

-Eu

charge-transfer bands of

AlO

(

= Ca

Ba) shift to the longer wavelength in order of Ca

Ba. The replacement of

in Sr

AlO

by La

Gd and Lu was studied. The dependence of the integrated luminescence intensities on Eu

concentration was presented. The lifetimes of Sr

-AlO

and Sr

AlO

were analyzed.
