Specifics of luminescence of nanoclusters consisting of InP@ZnS colloidal quantum dots stabilized by oleylamine

详细

Spectral, luminescent, and kinetic characteristics of nanoclusters of hydrophobic colloidal quantum dots (CQDs) of the core@shell type InP@ZnS stabilized by oleylamine have been studied, with the nanoclusters consisting of CQDs of two average sizes: with core diameters of 2.1 and 3.0 nm. For the nanoclusters consisting of the particles of any of these kinds, the experimental data indicate the occurrence of Förster resonance energy transfer with an efficiency of about 50%. For the mixed nanoclusters, energy transfer has not been observed within the experimental error.
