Abstract: The synthesis and optical properties of Eu3+ in SrAl12O19 nanophosphor have been studied. All the phosphors were prepared by combustion synthesis and characterized by XRD, EDS, TGA, DTA, particle size analyzer and photoluminescence measurements are carried out. The XRD characterization shows the formation of hexagonal crystalline SrAl12O19 matched with the JCPDS file no. 00-026-0976. SEM and EDS show the formation of nanophosphor and the presence of aluminium, strontium, europium and oxygen. Luminescent characterization shows the emission at 580 nm (yellow) in the visible region by the 858 nm infrared excitation. These results indicate that the Eu doped material is a promising yellow colour fluorescence powder used in colour display or yellow-LED light device using LASER diode as an excitation source.
