摘要：
A spectroscopic investigation on the effect of Ce3+ co-doping in fluoride KY3F10:Pr3+ crystals is presented. In particular spectroscopic measurements of three different samples of KY3F10 crystal doped with 0.3at% Pr3+ and co-doped with 0at%, 0.17at% and 0.3at% Ce3+ 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-3(0)-D-1(2) levels of Pr3+ and F-2(7/2)-F-2(5/2) of Ce3+. Data exhibit that this effect is strictly related to the Cerium concentration. (C) 2010 Elsevier Ltd. All rights reserved.
