Luminescence and Structure of Potassium Fluorooxalatozirconates

Аннотация

The X-ray luminescence of potassium fluorooxalatozirconates was studied. A high emission intensity was established for KZrF₃C₂O₄ · 3H₂O. Potassium fluorooxalatozirconates and fluorine compounds with known structures were compared by their X-ray luminescence. From the maximal luminescence intensity, it was established what atoms (F* or O*) were responsible for the luminescence of fluorooxalatozirconates. The composition of their polyhedra was suggested based on IR and X-ray luminescence spectra. It was shown that water in hydrated fluorooxalatozirconates has a crystallization character.
