Effect of heat treatment on properties of ytterbium and lanthanum co doped yttri

5 at.-% Yb3+ doped (La0.10Y0.90)2O3 transparent ceramics are fabricated by using commercial nanopowders in H2 atmosphere. Effect of the heat-treatment on the structure, spectral properties of (Yb0.05La0.10Y0.85)2O3 transparent ceramics is investigated. Laser grade ceramic samples are fabricated, and
