Abstract

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 (³P₀ → ³H₄, ³P₀ → ³F₂) 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.
