J. Legendziewicz et al., PREPARATION AND SPECTROSCOPY OF LANTHANIDE SINGLE-CRYSTALS WITH ISOLEUCINE, Acta Physica Polonica. A, 84(5), 1993, pp. 917-923
Single crystals of lanthanide complexes (Ln = Pr, Nd, Eu) were obtaine
d from aqueous solutions. Optical properties of the title compound are
investigated by absorption, excitation, and emission spectra. Probabi
lities of electronic transitions were analysed and participation of vi
bronic components in the spectra were found. Temperature effect on the
spectra was studied and analysed in terms of cooperative interaction.
