Förster-like nonexponential energy transfer kinetics in doped nanoparticles

Computer simulation of the static donor–acceptor energy transfer in samples containing impurity-doped nanoparticles of identical size and in a bulk crystal was performed, compared, and analyzed. A new double nonexponential decay law for nanoparticles was found and explained by two stages of quenching – that of bulk donors and donors on the surface.
