Problems of High-quality Doped Y2O3-ceramics Fabrication

KnE Engineering / Breakthrough directions of scientific research at MEPhI: Development prospects within the Strategic Academic Units / Pages 113–120

Abstract

Tm:Y2O3 , Ho:Y2O3 and Yb:Y2O3 ceramic samples were fabricated using different heat treatments modes. La2O3 (0.5 mol.%) and ZrO2 (1.5 mol.%) were used as sintering additives. Based on the investigation of structural properties of obtained samples, annealing mode was adjusted, and another set of samples with better optical quality was fabricated. In-line transmittance of the latter samples is 70% at 400nm and 75.6% at 600nm.
