Combustion synthesis and characterization of nanosized powder SrAl2O4:Eu2+ phosphor

A stoichiometric SrAl2O4:Eu2 nanosized powder was synthesized by combustion synthesis using urea at 500°C. The crystal structure, element and phase composition, and particle size were analyzed with the aim to study the properties of nanosized SrAl2O4:Eu2 green phosphor and its application. X-ray D...
