Absorption and luminescence spectra of dysprosium compound in non-aqueous solutions. Spectral intensity analysis.

Abstract

Absorption and luminescence spectra of dysprosium compound were measured in non-aqueous solutions (alcohols, amides) within the region 5500 – 35000 cm −1. The oscillator strengths of the f-f absorption bands were determined. The intensities of the Dy +3 ground state absorption were analyzed based on the Judd-Ofelt theory. A polarizability effect on the intensity of f-f transition was considered. The quenching mechanism of luminescence of the 4F 9 2 level for Dy +3 ion in non-aqueous solutions was discussed.
