详细

Colloidal indium phosphide quantum dots with a thin shell of zinc sulfide doped with manganese have been synthesized. Nanoclusters were fabricated based on the obtained nanocrystals. The effect of doping of nanocrystals on the process of Förster resonance transfer of electronic excitation and the spectral and luminescent properties of nanoclusters was studied for the first time. It has been shown that the luminescence of such clusters is radically different from the luminescence of undoped clusters and depends on the size of the nanocrystals. It is shown that the composition of particles participating in Förster transport depends on the moment of observation.
