Antiquenching effect of lanthanide .beta.-diketonate complexes on the photoluminescence of quantum-confined cadmium sulfide clusters
Titration of quantum-confined (Q-sized) CdS clusters in inverse micelle solutions with dilute lanthanide {beta}-diketonate (Ln(fod){sub 3}, Ln = Pr, Dy, Gd, Ho, Yb; fod = 6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octanedionato) complexes yields an enhancement in CdS photoluminescence (PL) ranging f...

| description | Titration of quantum-confined (Q-sized) CdS clusters in inverse micelle solutions with dilute lanthanide {beta}-diketonate (Ln(fod){sub 3}, Ln = Pr, Dy, Gd, Ho, Yb; fod = 6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octanedionato) complexes yields an enhancement in CdS photoluminescence (PL) ranging from 69% to 240%. The optimal magnitude of this antiquenching effect is dependent on the spectral characteristics of the parent Q-CdS cluster. The observed changes in PL areas clearly fit a Langmuir adsorption isotherm from which an average adduct formation constant (log K{sub f}) of 4.71 is determined, irrespective of choice of the lanthanide ion. |
