A microcrystalline Sr2P202:Eu2+ pyrophosphate-based phosphor was prepared by the modified solid-state diffusion. The crystalline phases were recognised using X-ray diffraction and surface morphology was studied by scanning electron microscope. Photoluminescence properties were investigated under ultraviolet-ray excitation. The Sr2P207:Eu2+ exhibits unique colour: a blue band centred at 430 nm originating...
This Letter reports the synthesis of Dy3+ ions-doped Ca3Al2O6 phosphor by combustion method. The prepared Ca3Al2O6:Dy3+ phosphors were characterised by X-ray diffraction, CIE colour coordinates, scanning electron microscope and photoluminescence spectroscopy. The characteristic intra-configurational 4f emissions of Dy3+ were observed in the emission spectra. The combination of the 485 nm blue emission...
