Upconversion emission from 3P0 level of Pr 3+ has been observed on excitation with 496.5 nm line of Ar + laser when Pr3+ and Eu3+ are codoped in oxyfluoroborate glass. No fluorescence is observed when only Pr3+ is present in the glass but even a small amount of Eu3+ leads to this fluorescence (3P03H4, 3P03F2) along with fluorescence from 5D0 level of Eu3+. The observed fluorescence of Pr3+ has been explained as being due to energy transfer from a pair of Eu3+ ions to a pair of Pr3+ ions.
