Abstract: | We have studied the luminescent properties of lead fluoride silicate nanostructured glass-ceramics doped with ytterbium and erbium ions. We have measured luminescence spectra of glass-ceramics in the visible and near-IR ranges at temperatures of 300 and 77 K and under their pumping at a wavelength of 975 nm. We have examined changes in the luminescence spectra of glass-ceramics depending on the time of their secondary thermal treatment, concentration of dopant ions, specimen temperature, and power of excitation radiation. |
