摘要
fd-excitation, absorption, reflection, and df-emission spectra presented in the literature on Eu2+ in inorganic compounds have been gathered and re-analyzed. Emission wavelength, width of the emission band, absorption wavelength, Stokes shift, and redshift pertaining to Eu2+ in more than 300 different compounds (fluorides, chlorides, bromide, iodides, oxides, sulfides, selenides, and nitrides) are presented. From the data, it is possible to predict for each of the 13 lanthanide ions (La2+, Ce2+, Pr2+, until Yb2+), doped in any of the compounds compiled, the energy of the transition from the 4fn ground state to the first 4fn−15d level and also the energy of df-emission. A brief overview on the relationships between redshift, Stokes shift, and the width of the emission with the type of compound is given.
