Photoluminescence investigation of the carrier recombination processes in ZnO quantum dots and nanocrystals
The carrier recombination processes in ZnO quantum dots 4 nm in diameter , ZnO nanocrystals 20 nm in diameter and bulk ZnO crystal have been studied using photoluminescence PL spectroscopy in the temperature range from 8.5 to 300 K. The obtained experimental data suggest that the ultraviolet PL in ZnO quantum dots originates from recombination of the acceptor-bound excitons for all temperatures...
متن کاملCarrier concentration dependent optical and electrical properties of Ga doped ZnO hexagonal nanocrystals.
Colloidal trivalent gallium (Ga) doped zinc oxide (ZnO) hexagonal nanocrystals have been prepared to introduce more carrier concentration into the wide band gap of ZnO. The dopant (Ga) modifies the morphology and size of ZnO nanocrystals. Low content of Ga enhances the optical band gap of ZnO due to excess carrier concentration in the conduction band of ZnO. The interaction among free carriers ...
متن کاملControlling carrier densities in photochemically reduced colloidal ZnO nanocrystals: size dependence and role of the hole quencher.
Photodoped colloidal ZnO nanocrystals are model systems for understanding the generation and physical or chemical properties of excess delocalized charge carriers in semiconductor nanocrystals. Typically, ZnO photodoping is achieved photochemically using ethanol (EtOH) as a sacrificial reductant. Curiously, different studies have reported over an order of magnitude spread in the maximum number ...
متن کاملAnnealing temperature and environment effects on ZnO nanocrystals embedded in SiO2: a photoluminescence and TEM study
We report on efficient ZnO nanocrystal (ZnO-NC) emission in the near-UV region. We show that luminescence from ZnO nanocrystals embedded in a SiO2 matrix can vary significantly as a function of the annealing temperature from 450°C to 700°C. We manage to correlate the emission of the ZnO nanocrystals embedded in SiO2 thin films with transmission electron microscopy images in order to optimize th...
متن کاملSpontaneous superlattice formation of ZnO nanocrystals capped with ionic liquid molecules.
Size-dependent 3D superlattices have been fabricated from ZnO nanocrystals capped with ionic liquid components; on the basis of X-ray diffraction, two packing modes, that is, hexagonal and face-centered cubic close packings, have been discovered for the superlattices consisting of the ZnO nanocrystals as building blocks.
