Abstract: | The absorption and fluorescence spectra of Pr(3+) doped in tellurite glass has been recorded and analyzed in terms of Judd-Ofelt theory. The lifetime of (3)P(0) and (3)P(1) levels has been measured. Fluorescence quenching has been observed for higher concentrations of Pr(3+) ion. The temperature dependence of the fluorescence intensity and the lifetime of the (3)P(0) level has been investigated and found that they decrease with the increase of the temperature. |
