Photoluminescence properties of SrLa2SiO6: Eu phosphor

The present paper reports the synthesis and Photoluminescence (PL) studies of the SrLa2SiO6 phosphor doped with Eu for different concentrations 0.1, 1.0, 1.5, 2.0 mole percentages respectively. The phosphor was synthesized using the standard solid state reaction technique and ground using mortar and pestle, fired at 1200 °C for 3 hour with heating rate of 5°C/min in a muffle furnace. The powder phosphors were characterized by X-ray diffraction and Scanning electron microscopy. The Photoluminescence (PL) excitation spectra were recorded for different Eu concentrations monitoring at 626 nm, and shows different emission peaks at 234, 254, 269 and 290nm. The Photoluminescence (PL) emission of Eu doped SrLa2SiO6 phosphor was recorded for different Eu concentrations, and show peaks at 365, 468, 514, 541, 589, 597, 615 and 627 nm with good intensity, these are mainly due to Eu3+ electron transitions.
