Spectroscopy of Ho:Y<sub>2</sub>O<sub>3</sub> transparent ceramics: Effect of YF<sub>3</sub> addition
Transparent ceramics of Holmium-doped yttria (Ho:Y 2 O 3 ) were fabricated by Hot Isostatic Pressing at 1720 °C / 190 MPa in argon, and the effect of YF 3 addition on their microstructure, optical, vibronic and infrared emission properties was studied. The fluorine addition improves the ceramic transparency, accelerates the grain growth and enhances the luminescence lifetimes of Ho 3+ states responsible for emissions at 2 µm and 3 µm.
