Mechanoluminescence by Impulsive Deformation and Photoluminescence of SrAl2O4:Eu Phosphor Prepared by Combustion Synthesis

SrAl2O4: Eu was synthesized by combustion method. Mechanoluminescence (ML) and Photoluminescence (PL) were studied. Time vs ML intensity plot shows two peaks. ML intensity increases with load applied and it is regained by UV irradiation. Photoluminescence shows intense emission in green region. PACS: 78.60.Mq; 78.55.Hx
