Abstract
The present paper reports the Photoluminescence (PL) spectra of Erbium and lithium doped Gd2O3 phosphor. Gd2O3:Er3+/Li+ Phosphor was synthesized by combustion synthesis method. The Phosphor was characterized by using X-ray diffractometer (XRD), Scanning Electron Microscope (SEM), Transmission Electron Microscopy (TEM), and photoluminescence emission spectra. Sample was characterized by XRD analysis and particle size was calculated by Debye-Scherrer formula The XRD patterns reveal that prepared Gd2O3:Er3+/Li+ phosphor have monoclinic crystal structure and particle size of 11Â nm. The photoluminescence emission spectrum was monitored at 976Â nm excitation and the corresponding emission peaks at blue, green and red emissions are reported. The emission spectra was monitored as a function of Li+ ion concentration.
