Europium- and dysprosium-doped strontium magnesium silicate powder with different concentration ratios of dysprosium were synthesized using solid-state reaction. The XRD pattern confirmed the proper preparation of the sample. The prepared phosphors were characterized using photoluminescence excitation and emission spectra. Prominent blue color emission was obtained under ultraviolet excitation. The thermoluminescence (TL) glow curves of the sample were measured at various delay times. With increased delay time, the intensity of the TL peak decays and the position of the TL peak shifts towards a higher temperature, indicating the considerable retrapping associated with general order kinetics.
