Abstract:The present paper reports the combustion synthesis of Yb3+ doped GdAlO3 phosphors. The structural characterization and luminescence spectra of Yb3+ doped GdAlO3 phosphors have been discussed. The effects of variable concentration of Yb3+ on Photoluminescence (PL) behavior were studied. The structural characterization was done by X-ray diffraction (XRD) and Transmission electron microscope technique (TEM). The good connectivity with grains and the semi-sphere line structure was found by TEM. The functional group analysis was carried out by Fourier transform infrared (FTIR) spectroscopic techniques. The prepared phosphor gives emission spectra in visible as well as NIR region. Both emissions were studied as a function of Yb3+ concentration. The emission intensity variation with Yb3+ ion concentration for visible and NIR region were discussed separately. The NIR emission luminescence of GdAlO3:Yb3+ phosphor luminescence continuously increases with increasing Yb3+ ion concentration.
