Synthesis and characterization of Dy activated MgSrAl10O17 phosphor for luminescence

MgSrAl10O17:xDy3 nanophosphors were fabricated by combustion method for different concentrations (x = 0, 0.0005, 0.001,, 0.005, 0.01 and 0.02 mol) of Dysprosium (Dy). The synthesized nanophosphors were characterized by XRD, SEM, and PL. The XRD (X-ray diffraction) showed crystalline hexagonal structure with preferred orientation of (107) plane. SEM (Scanning electron microscope) result shows the formation of nanosheets in irregular shape. The PL (photoluminescence) characterization of MgSrAl10O17:0.02 Dy3+ phosphor exhibits two main emission peaks at 484 and 575 nm due to Dy3+ ion. When excited with 350 nm wavelength, emission of the Dy3+ luminescence is close to white region and hence MgSrAl10O17:x Dy3+ phosphor can be a good candidate in solid state lighting for white light emission.
