Abstract: Sr2CeO4: Er3+ Phosphor was synthesized by high temperature Solid state reaction method. Using oxides as a raw materials and Erbium was used as an activator. XRD, SEM, EDAX and Photoluminescence spectra were using to investigation the formation process, microstructure and luminescence properties of the synthesized phosphor. The result shows orthorhombic structure and average crystallite size is 35 nm. The excitations are recorded by monitoring 470nm wavelength. All the phosphors are excited with 254, 275 and 340nm. When the phosphors are excited with various excitations, the basic Sr2CeO4 emission is found and the descending side i.e. 500 – 600nm contains the overlapped spiky emissions at 470, 527, 536, 545 and 558nm are clearly seen which the Er3+ emissions are basically. The excitation spectra of Sr2CeO4: Er3+phosphor display broad band with two peaks the former peak is stronger than the later one; this broad band is due to the charge transfer band of the Ce4+ ion. The emission spectrum of Sr2CeO4: Er3+ phosphor shows broad band spectra with peak around 470nm with the excitation by a radiation of 262nm. The emission of Sr2CeO4: Er3+for the excitation 262nm was emits bluish Green light and the emission spectra shows a broad band with peak around at 470, 527 536, 545, and 558 nm
