Host Lattices

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.

The Rare Earth

By activation of the cubic garnet host lattice Gd3Te2Li3O12 with trivalent rare earth ions the most intense visible emission is observed for Ln3+ = Eu, Tb. Energy transfer from Gd3+ to Sm3+, Eu3+ or Dy3+, from Tb3+ to Eu3+ and from Er3+ to Tm3+ has been found to occur. The luminescence properties are strongly influenced by the substitution of Te6+ by W6+ (systems Gd3-xLnxTe2-yWyLi3O12)

Ir Emission

By activation of the host lattice Sr3La2W2O12 with the trivalent rare earth ions Nd, Ho. Er. Tm and Yb an intense IR emission is observed, which can be sensitized by energy transfer from Nd3+ to Yb3+, from Er3+ to Ho3+ or Tm3+, from Tm3+ to Ho3+, and from Yb3+ to Ho3+ or Tm3+. For all other couples of trivalent rare earth ions no significant energy transfer is detected.

Trivalent Rare Earth

By activation of the host Gd3Te2Li3O12 with the trivalent rare earth ions Ln3+ = Pr, Sm, Eu, Tb-Tm and of Y3Te2Li3O12 with Ln3+ = Pr, Eu, Tb 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.
