| The goal of this work was to investigate the spectroscopic properties of Pr3+ ions (of a comparable concentration of the order of 0.2 mol/dm3) embedded in the tellurite glass matrix, i.e. TeO2-WO3-PbO modified with lanthanum and lutetium oxides. The difference is that the last components of both glasses provide ions which are optically inactive within the 4f shell, since this shell is completely empty for La3+ ion and completely filled for Lu3+ ion. The absorption and fluorescence spectra of Pr3+ doped in tellurite glass has been recorded and analyzed in terms of the Judd-Ofelt theory. The studies of the glasses comprised ellipsometric, spectrophotometric and photoluminescence measurements. The ellipsometric studies yield the refraction index dispersion which appears to be quite similar for all the studied glasses. From the spectrophotometric measurements, the absorption spectra have been obtained which, for Pr3+-doped samples, have been analyzed in terms of the Judd-Ofelt theory. Finally, the photoluminescence studies demonstrate a clear visible emission from 3P0 level to lower-lying states of Pr3+ ion. |
