Encapsulation of Ag nanoparticle-carbon composite and enhancement of visible light ZnO nanorods photodiode
نویسندگان
چکیده
Surface modification on zinc oxide nanorods (ZnO NRs) by encapsulating with silver nanoparticles-carbon (Ag NPs-C) composite was done and its characterisation undertaken. Field emission scanning electron microscopy (FESEM) shows a thin film of Ag NPs-C the ZnO NRs. Diffuse reflectance spectroscopy (DRS) has higher in 320-380 nm range, small absorption peak at 320 due to NPs plasmonic effect. NRs encapsulated records broader slight red shift photoluminescence (PL) spectra. The introduces new energy states lattice structure, resulting more photosensitive longer wavelength (460 nm) compared unencapsulated which is ultraviolet (395 nm).

Encapsulation of nanoparticles into single-crystal ZnO nanorods and microrods
One-dimensional single crystal incorporating functional nanoparticles of other materials could be an interesting platform for various applications. We studied the encapsulation of nanoparticles into single-crystal ZnO nanorods by exploiting the crystal growth of ZnO in aqueous solution. Two types of nanodiamonds with mean diameters of 10 nm and 40 nm, respectively, and polymer nanobeads with si...

A novel technique for the selective photochemical synthesis of silver (Ag) nanoparticles (NPs) on ZnO nanorod arrays is established by combining ultraviolet-assisted nanoimprint lithography (UV-NIL) for the definition of growth sites, hydrothermal reaction for the position-controlled growth of ZnO nanorods, and photochemical reduction for the decoration of Ag NPs on the ZnO nanorods. During pho...

The ZnO-CdS core-shell composite nanorods with CdS shell layer thicknesses of 5 and 20 nm were synthesized by combining the hydrothermal growth of ZnO nanorods with the sputtering thin-film deposition of CdS crystallites. The microstructures and optical properties of the ZnO-CdS nanorods were associated with the CdS shell layer thickness. A thicker CdS shell layer resulted in a rougher surface ...

Au and Ag hybrid hexagonal nanodisks were synthesized on ZnO nanorods' (0002) surface via a new two-step deposition-annealing method. The structural, compositional, as well as optical investigations were carried out systematically to find out the nanodisks' formation mechanism and optical enhancement effect. It was shown that the core-shell Au/Ag nanodisk can be formed under rapid annealing tem...
