Samarium-doped monoclinic CaAl2O4 phosphor was prepared at furnace temperatures as low as 500°C in a short time of 5min by using the combustion route. Powder X-ray diffraction and scanning electron microscopy studies were used to characterize the prepared combustion powder. Photoluminescence spectra revealed that samarium ions are present in trivalent oxidation states. The CaAl2O4:Sm exhibits two...
