Abstract

Site‐selective photoluminescence spectroscopy of Ho³⁺ ions in single‐crystal KYF₄, measured with a Fourier‐transform spectrometer at 80 and 2 K sample temperatures, gives evidence for two dissimilar classes of crystal‐field sites. Three similar sites contribute to each class giving a total of six sites in agreement with recent crystallographic results. Analysis of crystal‐field splittings indicates that only one of the classes can contribute to Yb→Ho upconversion green lasing in (Yb,Ho):KYF₄.
