By activation of the new host lattice Ca3La2Te2O12 with trivalent rare earth ions an emission in the visible (Ln3+=Sm, Eu, Tb, Dy, Ho, Er, Tm) or near infrared region (Nd, Ho, Er, Tm, Yb) is observed. Energy transfer from Nd3+ to Yb3+ , from Er3+, Yb3+ to Ho3+ and from Yb3+ to Tm3+ has been found to occur. The excitation, emission and diffuse reflectance spectra are analyzed.
