The nanocrystals size was 5 nm and 20 nm and was controlled by the mode of high-temperature annealing. It was determined that as a result of the quantum-dimension effect a considerable spectrum modification of the vibrational state takes place in nanocrystals Y2SiO5:Pr3+. The concentration decay 1D2 - luminescence of the activator ions in nanocrystals Y2SiО5:Pr3+ was investigated. It was determined that in the result of the activator ions nonuniform at the nanocrystal Y2SiО5:Pr3+ size already at the concentration of 0.5 mol % the ordered phase on the luminescence decay curve 1D2- is observed that is not observed in bulk crystals Y2SiО5:Pr3+ even at the concentrations of 1.8 mol %.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
