A spectroscopic investigation on the effect of Ce co-doping in fluoride KYF:Pr crystals is presented. In particular spectroscopic measurements of three different samples of KYF crystal doped with 0.3at% Pr and co-doped with 0at%, 0.17at% and 0.3at% Ce are discussed. Details on the growth of the crystals are also reported. Measurements were performed in the temperature range 10 - 300 K. Fluorescence and lifetime measurements have shown a cross relaxation between P - D levels of Pr and 2F -F of Ce. Data exhibit that this effect is strictly related to the Cerium concentration.
