چکیده انگلیسی
The present paper reports infrared spectroscopy and luminescence spectra of Yb3+ doped ZrO2 nanophosphor. Sample was prepared by combustion synthesis method (CSM) for the variable concentration of ytterbium. The low temperature synthesis method was suitable for large scale production present method is an eco-friendly method as well as less time taking method as compared to other methods. The synthesized samples were characterized by X-ray diffraction (XRD) technique; scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR) technique. The crystal size was calculated by Scherer's formula. The particle size distribution in prepared sample was determined by SEM and TEM study. The photoluminescence spectra was recorded under the 980Â nm laser excitation with the variable concentration of ytterbium. Here the PL intensity increases with increasing the concentration of ytterbium. No concentration quenching were observed. The PL emission spectra shows intense emission peaks at 987, 998 and 1021Â nm all in infrared regions.
