Abstract:
In this work we evaluate structural and optical properties of ZnO
nanoparticles grown by wet chemistry method. Light emission properties
of these nanoparticles are studied with cathodoluminescence and micro-
photoluminescence. Even at the room temperature excitonic emission is
well resolved, due to high exciton binding energy of ZnO. Decay kinetics of
photoluminescence emissions and efficiency of inter-nanoparticles energy migration is evaluated from maps of in-plane variations of photoluminescence
decay times measured in microphotoluminescence setup.
