Processes of excitation energy transport in EuPO₄ and EuP₃O₉ nanocrystals

Анотація:

Processes of excitation energy transport were investigated for EuPO₄ and EuP₃O₉ nanocrystals, in which Eu³⁺ ions form three- and one-dimensional subsystems, respectively. It was determined that for EuPO₄ nanocrystals ⁵D₀ luminescence quenching manifested itself even at low temperatures due to effective phonon-assisted energy migration. At the same time, for EuP₃O₉ nanocrystals no influence of energy migration on the luminescence quenching was observed in the whole temperature range from 10 to 293 K that can be ascribed to modification of phonon spectra for EuP₃O₉ nanocrystals as compared to their bulk counterparts.
