Abstract

Eu and Dy activated SrAl₂O₄ with long persistence phosphors has been synthesized by combustion method in low temperature. Influence of the ratio of Al and Sr, presence of additivs, etc. on the properties of the sample was studied. The results indicate that the best temperature of the oven for its synthesis is about 500 C. The afterglow can last more than 12 hours, and the emission spectra wave length is 520 nm. It is more bright, has low hardness, low temperature of synthesis and requires less time in synthesis when compared with products synthesized by high temperature solid-phase reactions.
