摘要：

Series of Sr2MgAl22O36:Ce3+, Sr2MgAl22O36:Dy3+ and Sr2MgAl22O36:Ce3+,Dy3+ phosphors were synthesized by urea-assisted combustion method. The identification of phase and morphology of the prepared samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Photoluminescence excitation (PLE) and emission spectra of the as-prepared samples were investigated. Photoluminescence studies revealed that the luminescence intensity of Ce3+ ion increases with increasing concentration in Sr2MgAl22O36:Ce3+ and no concentration quenching have been witnessed. Similar trend was observed for Sr2MgAl22O36:Dy3+ with increasing Dy3+ concentration. The energy transfer from Ce3+ to Dy3+ in Sr2MgAl22O36 host has been achieved successfully to produce white light emission. The calculated Commission Internationale de L'Eclairage (CIE) chromaticity coordinates for the Sr2MgAl22O36:Ce3+, Dy3+ phosphor are (x = 0.302, y = 0.357). The values of CIE chromaticity coordinates and correlated color temperature (CCT) of 6798 K endorse Sr2MgAl22O36:Ce3+, Dy3+ phosphor as potential candidate for cool white-light emission.
