The structural and optical characteristics of polyvinyl alcohol (PVA) doped with different concentration of Nd2O3nanoparticles to use an active media for polymer laser were studied. The PVA polymer was considered as the host and Nd2O3nanoparticles as the active element. The media as a thin film was prepared using spin coating technique. Structural properties of layers were investigated by X-ray diffraction (XRD) pattern and atomic force microscope (AFM) technique. The effect of the concentrations of the neodymium source on the optical properties of Nd2O3/PVA thin films was investigated through UV-Vis absorption spectroscopy and their optical band gap was evaluated. Also, the FTIR and fluorescence spectra of the samples were detected. The fluorescence spectra of films showed that the maximum wavelength occurred at 568[Formula: see text]nm with no significant shift.
