Herein the synthesis, structural characterization and photoluminescence behavior of Er/Yb activated Gd(2)O(3 )phosphor is presented. Yb and Er-doped Gd2O3 phosphor samples were synthesized through the conventional solid-state-reaction (SSR) method and their structural aspects were examined by the X-ray diffraction (XRD) analysis. Morphology of the prepared phosphor samples was examined by Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). The emission and excitation spectra of the prepared phosphor samples were systematically recorded. They displayed intense emission in the visible region. The excitation spectra recorded at 613 nm emission showed two prominent excitation peaks at 254 and 278 nm. Similar to that excitation with various emission peaks were also observed correspondingly at 467, 545 and 613 nm. The present study gives basic information about the transition of (Yb, Er) activated rare earth as well as the spectroscopic parameters of the prepared p
