Abstract

Owing to its poor water resistance

the application of SrAl

:Eu

phosphors is limited seriously. In this paper

a rapid combustion method was introduced into the surface treatment of SrAl

:Eu

phosphors. X-ray diffraction

X-ray photoelectron spectroscopy

scanning electron microscopy

photoluminescence spectrophotometry and pH measurements were employed to characterize the treated and untreated phosphors. Experimental results showed that a compact layer was coated on the surface of SrAl

:Eu

phosphors

which effectively improved the water resistance of phosphors.
