Effect of solvents on oscillator strengths of supersensitive transition of neodymium, holmium and erbium ions in solutions of complexes with N-benzoyl-N-phenylhydroxylamine

The solvent influence on the intensity of the absorption bands corresponding to the supersensitive transition (sst) of the ions Nd, Ho, Er in the solutions of the complexes with N-benzoyl-N-phenylhydroxyamine (b.p.h.a.) was studied in the paper. Oscillators forses (P) were determined by using recorded absorption spectras of the complexes in the solvents under studies, taking into consideration concentration of the rare-earth elements (r.e.e.). It was shown earlier, that in case of switch-over from one solvent to another one and increase of the oscillator force of one element, the proportional increase of the oscillator force of the other element was observed. This research demonstrated that with the increasing of Psub(Er), Psub(Nd) and Psub(Ho) are proportionally increasing
