Well-aligned, densely distributed ZrO2 nanorod arrays were fabricated using a non-catalytic, templatefree metal–organic chemical vapour deposition process at a reaction temperature of 1000 C. The reaction temperature was found to play a key role in product morphology, with particle thin films obtained at 550 C and nanorod arrays produced at 1000 C. Increasing the reaction temperature led to the...

We have fabricated inverted heterojunction solar cell devices incorporating [6,6]-phenyl-C(61)-butyric acid methyl ester/poly(3-hexylthiophene) core/shell nanorod arrays by using an anodic alumina oxide template. The internal quantum efficiencies and external quantum efficiencies of these core/shell nanorod inverted solar cells were higher than those of the corresponding conventional inverted b...

We report a simple wet-chemical synthesis of ∼5 nm diameter ZnO nanorod arrays at room temperature (20 °C) and normal atmospheric pressure (1 atm) and their optical properties. They were single crystalline in nature, and grew in the [001] direction. These small diameter ZnO nanorod arrays can also be synthesized at 0 °C. Control experiments were also conducted. On the basis of the results, we p...

In this study, we report the concerted fabrication process, which is easy to transform the size of active emitting area and produce polarized surface light, using the electric-field-assisted assembly for horizontally assembled many tiny nanorod LEDs between two metal electrodes. We fabricate the millions of individually separated 1D nanorod LEDs from 2D nanorod arrays using nanosphere lithograp...

One-dimensional nanorods open up many new device applications. As one of the semiconductor nanorods, ZnO-based nanorods have been studied for electronic and photonic nanodevice applications. Recently, we developed catalyst-free metal-organic chemical vapor deposition of ZnO nanorods and employed these ZnO nanorods for electrical and optical nanodevice applications. In this presentation, I will ...

Solar photoelectrosynthesis of methanol was driven on hybrid CuO-Cu(2)O semiconductor nanorod arrays for the first time at potentials ~800 mV below the thermodynamic threshold value and at Faradaic efficiencies up to ~95%. The CuO-Cu(2)O nanorod arrays were prepared on Cu substrates by a two-step approach consisting of the initial thermal growth of CuO nanorods followed by controlled electrodep...

In this paper we analyze the dependence of the resonance wavelength and mode formation of an optical gold nanorod antenna on its geometrical parameters in the wavelength range 500–1400 nm. In particular, we prove that nanoantennas differ from RF counterparts, since the minima and maxima, i.e., nodes and anti-nodes, of the resonant modes do not go to zero and show very intense peak at the corner...

Bridged ZnO nanorod arrays on V-grooved Si(100) substrate were used as the photoanode of a photoelectrochemical (PEC) cell for water splitting. Photolithography followed by reactive ion etching was employed to create a V-grooved structure on a Si substrate. ZnO nanorod arrays were grown via a hydrothermal method. The light trapping and PEC properties are greatly enhanced using the bridged ZnO n...

Sol-gel derived sulfur modified and pure ZnO nanorod were prepared using zinc chloride and thiocarbamide as raw materials. Prepared nanorods were characterized by means of X-ray diffraction (XRD), thermogravimetry- differential scanning calorimetry (TG–DSC), UV- Vis absorption spectroscopy, Brunauer Emmett Teller (BET) specific surface area and Barrett Joyner Halenda (BJH) pore size distributio...

In this letter, we demonstrate a facile far-field approach to quantify the near-field local density of optical states (LDOS) of a nanorod using CdTe quantum dots (QDs) emitters tethered to the surface of nanorods as beacons for optical read-outs. Radiative decay rate was extracted to quantify the LDOS; our analysis indicates that the LDOS of the nanorod enhance both the radiative and nonradiati...
