Opis:: Vibronic spectra of Gd$\text{}^{3+}$ in Cs$\text{}_{2}$NaGdCl$\text{}_{6}$ were measured under one- and two-photon excitations. Following the vibrational analysis of the Cs$\text{}_{2}$NaGdCl$\text{}_{6}$ crystal an assignment of vibronic transitions was proposed. It was found that the vibronic transitions in one- and two-photon spectra are combined with the odd parity modes.

Opis:: Electron absorption and emission spectra of Eu$\text{}^{3+}$ ion in stoichiometric KEu(WO$\text{}_{4}$)$\text{}_{2}$ were measured at the temperature range 15-300 K. The oscillator strengths of f-f transitions and the Judd-Ofelt parameters were evaluated. The assignment of vibronic transitions is given and mechanism of emission decay is discussed.

Opis:: The optical excitation and emission spectra of Eu(III) in [Eu$\text{}_{x}$La$\text{}_{1-x}$(AP)$\text{}_{6}$](ClO$\text{}_{4}$)$\text{}_{3}$ centrosymmetric complex were measured. The vibronic transitions were observed in excitation and emission spectra. Following the vibrational analysis' of the infrared and Raman spectra of [Pr$\text{}_{x}$La$\text{}_{1-x}$(AP)$\text{}_{6}$](ClO$\text{}_{4}$)$\text{}_{3}$, the assignment of [Eu$\text{}_{x}$La$\text{}_{1-x}$(AP)$\text{}_{6}$](ClO$\text{}_{4}$)$\text{}_{3}$ vibronics was given The concentration effect on excitation and emission spectra was investigated. It was found that the vibronic intensities were changed upon the concentration effect. The intensive charge transfer bands were observed in blue region. Their intensities decreased with increasing concentration.
