Abstract
The present paper reports on the synthesis and characterization of Sr2CeO4 doped with La3+ and Eu3+ rare earth ions with (0.5%) concentration. The phosphor samples were synthesized using the standard solid state reaction technique. Analytical grade inorganic salts like Sr(NO3)2, CeO2, La2O3 and Eu2O3 were used as raw materials of assay 99.9% were weighed, mixed and ground in to fine powder using agate mortar and pestle. The samples were heated to 1200oC for 3 hours using muffle furnace with a heating rate of 5oC/min. All the samples were allowed to cool at room temperature in the same furnace. We have studied the effect of La: Eu co-dopant on the structural, morphological, and Photo luminescent properties of the samples using X-ray diffraction (XRD), SEM, PL, particle size analysis and CIE coordinates
