Abstracts

EN

Absorption and excitation spectra of lanthanides molybdates and tungstates were measured and analyzed. Probabilities of electronic transitions were analysed on the basis of the Judd-Ofelt theory. The significant differences of intensities were observed. Those differences could result from the symmetry changes, cooperative effects and electron-phonon interaction. The elucidation of intensities given by separate mechanisms needs further investigation.
