Raman spectra have been recorded for glasses in the binary systems CeO 2 ‐P 2 O 5 and Pr 2 O 3 ‐P 2 O 5 . The cerium phosphate glasses were prepared having different concentrations of CeO 2 and the praseodymium phosphate glasses with different ratios of Pr 3+ to Pr 4+ . The spectra indicate that both cerium and praseodymium enter the glass in modifying sites. We see no changes in the Raman spectra with Pr 3+ /Pr 4+ ratio. Measurements of the density and glass transition temperature are also reported.
