Low-temperature luminescence of nanosized SrAl2O4:Eu2+

A stoichiometric SrAl2O4:Eu2 nanosized powder was synthesized by a combustion method using urea at 500°C and calcination at 1000ºC. The luminescence properties were investigated and two luminescence bands at 450 nm and 512 nm were observed at lower temperatures. This luminescence in the green regio...
