Abstract
In this study Dy doped MgSrAl10O17:xDy3+ phosphor has been synthesized by Combustion method for different concentrations of Dy (x = 0, 0.0005, 0.001, 0.002, 0.005, 0.01 and 0.02). The synthesized phosphor was characterized for its thermoluminescence (TL) and photoluminescence (PL) properties that included TL glow curves and PL excitation & emission spectra . TL intensity was found to increase with increase in concentration of dopant Dy and was found to show best result for x=0.02. Further PL characterization of MgSrAl10O17:0.02Dy3+ phosphor exhibits two main emission peaks, at 484 and at 575 nm due to Dy3+ ion, when excited with 350 nm wavelength. So, emission of the Dy3+ luminescence is close to white region and hence MgSrAl10O17:xDy3+ phosphor can be a good candidate in solid state lighting for white light emission.
