| dc.description.abstractEn | After an investigation of the formation conditions of the intermediate phases existing in the systems Y2O3-P2O5 and Gd2O3-P2O5 (R/P = 4/1, 3/1, 1, 1/2, 1/3 and 1/5 (R = Y or Gd)) the luminescence characteristics of the Eu3+ ion substituted for the Y3+ or Gd3+ ions have been determined. The position of the O-2 -> Eu3+ charge transfer band shifts to higher energies with increasing P content, which results in high quantum efficiencies for several P-rich phosphates. With increasing P content the probability of the electric dipole transitions is reduced, in particular for the hypersensitive 5D a->7 F2 transition. This causes a shift of the colour point to the orange and lengthens the luminescence lifetime. The luminescence characteristics are compared with those of the red phosphors for display. | |
