4f^n-4f-=SUP=-n-1-=/SUP=-d-переходы в оптических спектрах трис(1,2,4-трифенилциклопентадиенильных)-комплексов трехвалентных лантанидов
Tris complexes of Ln3+ ions (Ln = La, Ce, Pr) with triphenyl-substituted cyclopentadienyl ligands were studied by optical spectroscopy. Emission of both 5d - 4f and 4f - 4f transitions was observed for Pr3+ complex. It was found that the strength of the crystal field formed by triphenyl-substituted cyclopentadienyl ligands in tris complexes is comparable to the case of sulfides, and as a result, red luminescence is observed for the Ce3+ compound. The quantum yield of photoluminescence is 20% for the latter.
