| Zusammenfassung | We report on the spectroscopic investigation of Pr3+ doped binary, ternary and quaterny fluoride compounds exhibiting photon cascade emission. Under vacuum ultraviolet (VUV) synchrotron excitation at wavelengths below 200 nm in the 4f5d bands of the Pr3+ ion the emission spectra show intraconfigurational 4f-4f transitions originating from the 1S0 and 3P0 multiplets. In the ternary and quaterny compounds investigated, i.e. Ca-, Sr-, Ba-, and Rb-fluorides, also broadband emission due to transitions from the 4f5d level of Pr3+ are observed. The different types of emission transitions observed in the compounds investigated were analyzed in detail. The internal quantum efficiency for the visible spectral range (390 nm - 750 nm), ηvis, is determined with the help of the Judd-Ofelt theory and the branching ratios of the 1S0 emission transitions. The dependence of this quantum efficiency ηvis from the ionic radius of the second cation (R2nd), the effective ligand distance and the coordination number is investigated. |
