Judd-Ofelt analysis and emission properties of Eu~(3+) ions in fluoroindate glasses

摘要

Optical absorption and emission spectra of Eu~(3+) ions in fluoroindate glasses have been investigated. From the experimental values of oscillator strengths with thermal correction, the Judd-Ofelt intensity parameters were obtained. These data are compared with Judd-Ofelt parameters also calculated from emission spectra. The spectroscopic parameters of Eu~(3+) ions in fluoroindate glasses were determined and compared to the values of fluorozirconate glasses.
