Synthesis of highly sinterable Tm,Ho:(Lu1-xScx)2O3 powders by spray co-precipitation for transparent ceramics: Influence of the variable x

Highly sinterable Tm,Ho:(Lu1-xScx)2O3 nanopowders were synthesized by a spray co-precipitation method. The influences of the calcination temperatures and x values on the morphology and composition of the powders were studied. The results indicated that the precursor gradually formed needlelike structures with increasing x values, and the powders calcined at 1100??C for 2?h exhibited the highest uniformity and sintering activity. Using the powders calcined at 1100??C, the Tm,Ho:(Lu1-xScx)2O3 ceramics with the highest in-line transmittance of 79.80% at 2090?nm were fabricated by vacuum sintering at 1550??C for 10?h and further hot isostatic pressing under 190?MPa?at 1700??C. Owing to the disordered crystal structure of the (Lu1-xScx)2O3, the grain size of the ceramics decreased from 1.72 ?m to 1.16 ?m, and the emission spectra showed some variation with increasing x values. This work demonstrates promise in facilitating the production of Tm,Ho:(Lu1-xScx)2O3 transparent ceramics for their use in 2 ?m ultrashort laser pulse and other applications.
