The optical properties of Ni2+ -ion impurities in a new crystal, the inverted fluoroperovskite BaLiF3, have been studied. In particular we have investigated the fine structure of the transition by means of absorption and emission spectra. By analogy to previous results we have assigned the structured absorption band around 1200 nm to the 3A2 ↠ 3Ti transition. Four zero-phonon lines are clearly visible in the absorption spectrum. The emission in the region 1250–1600 nm, due to the same 3A23T1 transition, consists of two sharp lines with their vibrational sidebands. © 1995, Taylor & Francis Group, LLC. All rights reserved.
