Abstract

Abstract: Oxyiodides of 15 rare earths, LnOI (Ln=La-Lu and Y) were prepared by a flux method under reducing atmosphere. LnOI obtained were checked by chemical analysis and X-ray diffraction method. The crystals of all of the oxyiodides belong to the tetragonal system. The crystal parameters of the compounds were compared with those of LnOCL and LnOBr. Anomaly of EuOI has been discussed.

Key words: Rare earth compounds, Oxyiodides, Preparation, Crystal structure, Sensitizer
