- Abstract
Phase pure Tb1–xYbxAl3(BO3)4 (x = 0 – 1) crystalline powders were prepared by the combustion synthesis method. Down-conversion experiments under UV excitation of 375 nm revealed optimal concentration of Yb x = 0.5 providing intensive green luminescence with 24% of quantum efficiency. Also up-conversion luminescence via energy transfer from Yb3+ to Tb3+ using a low power IR diode laser operating at 980 nm was achieved. Here the most powerful green emission was obtained with x = 0.1.
