As one of the most prevalent metal oxides on Earth, iron oxide, especially α-Fe2O3 or
hematite, has been the subject of intense research for several decades. In particular, the …

Zinc oxide (ZnO), with its excellent luminescent properties and the ease of growth of its
nanostructures, holds promise for the development of photonic devices. The recent …

We report a systematic investigation of both three-photon absorption (3PA) spectra and
wavelength dispersions of Kerr-type nonlinear refraction in wide-gap semiconductors. The Z …

Cu2O–Au nanocomposites (NCs) with tunable coverage of Au were prepared by a facile
method of mixing gold nanoparticles (Au NPs) with copper (I) oxide nanowires (Cu2O NWs) …

At carrier densities above the Mott density, Coulomb screening destroys the exciton
resonance. This, together with band-gap renormalization and band filling, severely affects …

Morphology-rich ZnO as a direct band gap II–VI semiconductor is a promising material for
photonic, optical, and electronic devices. Nanostructured materials have provided a leading …

ZnO nanoparticles embedded in the PMMA matrix were prepared by wet chemical synthesis.
The optical band gap of the ZnO nanoparticles decreases with increase in NaOH …

ZnO nanowires (NWs) grown by the hydrothermal method on fluorine-doped tin oxide glass
substrate were characterized by scanning electron microscopy, optical absorption …

The fabrication of an ultraviolet photodiode employing a single ZnO tetrapod nanocrystal is
reported. This diode structure is prepared by depositing W and Pt electrodes to form Ohmic …

We have studied ultrafast dynamics in thin films of Eu-doped zinc oxide (ZnO), prepared by
radio-frequency sputtering onto sapphire substrates. Following UV excitation of ZnO, a red …
