Raman spectra have been recorded for glasses in the binary systems CeO2 -P2 O5 and Pr2 O3 -P2 O5 . The cerium phosphate glasses were prepared having different concentrations of CeO2 and the praseodymium phosphate glasses with different ratios of Pr3+ to Pr4+ . The spectra indicate that both cerium and praseodymium enter the glass in modifying sites. We see no changes in the Raman spectra with Pr3+ /Pr4+ ratio. Measurements of the density and glass transition temperature are also reported. 相似文献
