　　报告摘要：

　　It was found that Tb or Pr could be used as the sensitizers of Eu emission upon VUV excitation. Addition of terbium do not need an assistance of Gd ions, contrary to Pr one. Such a process is much stronger that published earlier so called “photon cutting” processes. At the end an efficient energy transfer from the 5d levels of Tb3+ to Eu3+ occurs in the studied system. Finely the white luminescence was observed upon excitation of Tb3+ bands.
