We have studied the luminescence property of CaMoO4:Eu3+. The emission peaks at 590 (5D0→7F1) and 613 nm (5D0→7F2) for Eu3+ are observed after excitation 266 (i.e. Mo–O charge transfer band). peak intensity latter dominates over former indicating an asymmetric environment in EuO8 polyhedron or parity mixing. Luminescence increases significantly with co-doping Gd3+. This is ascribed to energy from Mo–O/Gd3+ Eu3+. annealing up 900 °C due extent decrease non-radiative rates. Very high values...
