High Stability and Long Afterglow of Green Strontium Aluminates Composed of SrAl2O4:Eu2+ and SrAl12O19:Eu2+ Crystals
This paper presents the stability and afterglow of strontium aluminates (SAO) consisting of SrAl2O4:Eu2+ and SrAl12O19:Eu2+. The maximum energy absorption and emission peaks were at 364 and 517 nm, respectively. Upon increasing the Eu2+ concentration, the decay time of SAO:Eu2+ decreased from 46.09 to 13.35 s. When the phosphor was heated to 110°C, the luminescence intensity decreased by only 10%. Furthermore, the SAO:Eu2+ exhibited high moisture resistance and long rechargeable persistent luminescence, hence, it is a promising material for digital optical data storage applications.
