Abstract

The red emitting phosphor Sr

AlO

was synthesized through the solid-state reaction technique. The structure

photoluminescence properties of Sr

AlO

were described. Under the excitation of UV and near UV light

the photoluminescence emission spectra can be assigned to the well-known transitions of Eu

from the initial state

to the final states

(

4). The two strong emissions peak at 590 nm and 622 nm

which arose from the

and

transitions of Eu

respectively. When the mole fraction of Eu

is 0.75

the emission intensity of the phosphor is the strongest. This phosphor is considered to be a potential red-emitting phosphor for NUV chip white LED.
