摘要
We have studied absorption and luminescence spectra of yttrium-aluminum garnets doped with Er3+ and Ce3+ ions, as well as co-doped with Er3++Ce3+ impurity ions. Luminescence of studied crystals was excited by cw laser radiation at the wavelengths 457 and 980 nm. We revealed obvious display of the energy transfer processes occurring in the impurity subsystem of a YAG: Er3++Ce3+ crystal.
