Abstract

Low temperature luminescence spectrum of holmium ions in monoclinic Rb ₂KHoF ₆ crystal was found to be well analyzable by the comparison with earlier studied cubic Cs ₂NaHoF ₆. The manifestation of the local symmetry influence on the strength of individual lines is found to be distinctive. In the absence of structural data, the local symmetry of holmium in Rb ₂KHoF ₆ is proved to be a non-centrosymmetric one. The concentration quenching of holmium luminescence in Rb ₂KHoF ₆ is found to be rather modest.
