Effect of fluorine addition on the microstructure and emission properties of Ho:Y2O3 transparent ceramics
Abstract
In this work, the role of fluorine doping on the microstructural and spectroscopic properties of Ho:Y₂O₃ transparent ceramics was investigated. The ceramics were fabricated by adding YF₃ powders to the primary composition, then sintered either a rapid sintering technique (Spark Plasma Sintering, SPS) or Hot Isostatic Pressing (HIP). As a result, fluoride appears to promote grain growth and porosity elimination, regardless of the sintering method. Spectroscopic study shows that limited F doping (4500 ppm YF₃) has no significant influence on the absorption and emission spectral profiles of Ho³⁺ ions, but it increases the luminescence lifetimes of the ⁵I₇ and ⁵I₆ manifolds giving rise to emission at 2 μm and 3 μm, respectively, especially for ceramics produced by a post-HIP treatment.
