In present work the optical properties of the highly transparent ceramics for lasers active media with wide emission bandwidth are presented. Ceramics has been synthesized from 1 at.% Yb3+ : Y2O3 nanopowders to which isovalent Lu3+ and Sc3+ and heterovalent Zr4+ ions were added for disordering the crystal structure. The emission bandwidth of Yb3+ ion on the 2F5/22F7/2 transition at a 50% level of the maximum luminescence intensity was 20-30 nm. Moreover, at a 25% level this bandwidth is covered by the bandwidth of the same transition but at lower 2F7/2 level and full bandwidth, at which it is more than 100 nm.
