Abstract

Praseodymium doped crystals and glasses are of interest with respect to their up-conversion ability. In order to establish the efficiencies of up-conversion we have measured and calculated radiative and non-radiative transition probabilities of the luminescent levels (³P₁ + ³P₀), ¹D₂ and ¹G₄ and measured their lifetimes and concentration dependence of the cross-relaxation rates. Critical radii of the cross-relaxation process are calculated to be for the ³P_i manifold and 12.8±0.5Å for ¹D₂.
These are compared with similar data in fluoride glass.
