[en] Mixtures of 0.4 mol ZnO and 0.6 mol Y2O3 activated with Bi and Eu or Bi and Dy were doped with Li+, Na+, K+, Rb+, and Cs+. For these luminophors the intensity of emission was found to be increased at 25 0C and 300 0C in comparison to the undoped mixtures. The excitation spectra of doped and undoped luminophors showed the maximum excitation in the region of 221 nm and 332 nm. By doping the excitability could be insignificantly improved. (author)
