Abstract
We report experimental investigations into the co-doping of Nd3+-Pr3+ ions in LFP glasses. The method used in this study is the melt quench technique. Several physical and structural properties were investigated in this work. The structural properties were investigated by FTIR (Fourier Transform infrared) and XANES (X-ray absorption near edge structure) spectroscopy. The location of the white line peak at ∼6210 eV and the intensity of L3-edge XANES of Nd depend on the ratio of O/Nd in the glass matrix. Several excitations exhibited the luminescence properties in the photo and near-infrared spectrophotometer. The excitation at 481 nm shows seven peaks in the Nd3+ and Pr3+ transitions in the visible region. Meanwhile, the near-infrared region shows three peaks of Nd3+ and Pr3+ transitions at ∼1.06 μm wavelength.
