Transfer of Electronic Excitation Energy in Nanoclusters of Colloidal InP/ZnS Quantum Dots Doped with Manganese Ions.

Manganese-doped colloidal indium phosphide quantum dots with a thin zinc sulfide shell have been synthesized. Nanoclusters were fabricated based on the obtained nanocrystals. The effect of doping of nanocrystals on the process of Förster resonance electronic excitation transfer and the spectral and luminescent properties of nanoclusters was studied for the first time. It has been shown that the luminescence of such clusters radically differs from the luminescence of undoped clusters and depends on the size distribution of nanoparticles included in the nanoclusters. It is shown that the composition of particles participating in Förster transport depends on the time point of observation. [ABSTRACT FROM AUTHOR]
