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

Authors:

Calyn, S.; Nazarov, Mihail; Nazida, AwangNor; Ahmad-Fauzi, M.

Summary:

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 Diffraction pattern revealed that the SrAl2O4:Eu2 crystallizes were a major phase, and Sr4Al14O25 as a secondary phase with a small amount of the dopant has no effect on the crystal structure of SrAl2O4. Crystalline structure can be observed and enhanced by calcination at 1000ºC with 2-h soaking time in a reductive atmosphere. Nucleation of particles occurs and forms a needle-like structure for SrAl2O4 and a star-like structure for SrAl2O4:Eu2 . This structure is unstable and agglomerates during calcination at 1000 °C to form a stable specific flower-like structure which enhances the glowing effect of the samples.
