Abstract
By activation of the host lattices Sr3La2W2O12 and Ca2La0,5Na0,5WO6 with the trivalent rare earth ions Ln3+ = Pr, Sm, Eu, Tb, Dy, Ho, Er a cathodoluminescence in the visible region is obtained. The influence of the electronic structure and concentration of the activator on the relative emission efficiency as well as the host lattice participation in the energy transfer processes are discussed.Keywords
