Abstract
The fluoresence spectrum of europium(+III) doped LaMgB5O10 was studied at 77 and 300K under U.V. and visible dye laser excitation. A phenomenological crystal field analysis was conducted on the basis of the observed 34 7 F 0-5 level energies. A descending symmetry method from D 2d to C 2v and C 2 symmetries was used in the simulation. D 2d simulation was found to be inadequate to describe the experimental energy level scheme whereas for C 2v symmetry a satisfactory r.m.s. deviation of 7·1 cm-1 was obtained. The decrease in symmetry to C 2 did not improve the simulation. The weak 5 D 0 → 7 F 0 transition intensity was found to correlate with the mixing of the 7 F 2,4 wave functions with the 7 F 00 one.Keywords
