  • Abstract
    The time-resolved luminescence was studied for ZrO2:Y single crystal and nanocrystals. The similar recombination centres were found in both single crystal and nanocrystals. Luminescence decay is within 200 ns in nanocrystals, whereas it extends to the microseconds in single crystal. It was shown that the defects responsible for transient absorption were not involved directly in radiative recombination process.
