Composition and structure of BCN films prepared by ion beam-assisted pulsed laser deposition

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2002)

Hao Ling Zhifeng Ying Jiada Wu Jian Sun Wei Shi

We report on the preparation of boron carbon nitride (BCN) thin films by pulsed laser ablation of a sintered B₄C target and the compositional and structural characterization of the films. The film preparation was performed with assistance of nitrogen ion beam from a Kaufman source. X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR) were used for compositional analysis and structural characterization. The results showed that the prepared films contain several chemical bonds such as B-N and C-N. The BCN films were found to show good adhesion to the substrates and have a high transparency from visible to near-infrared region. WE also grew films in nitrogen background without ion beam assistance and in vacuum. The atomic ratio of boron, carbon and nitrogen and the chemical bonds are strongly dependent on the deposition conditions. The ion beam assistance, i.e. the reactive nitrogen environment and the bombardment of the growing films by the energetic species in the nitrogen ion beam, is beneficial to the incorporation of nitrogen.

Fabrication of ZnO nanorods by pulsed Nd:YAG laser ablation deposition

Journal of Vacuum Science & Technology B Microelectronics and Nanometer Structures Processing Measurement and Phenomena (2009)

Yiqun Shen Ning Xu Jushui Lai Jian Sun Jiada Wu

ZnO nanorods were fabricated on Si (100) substrate by pulsed laser ablation of ZnO target with background O2 gas. Nd:YAG laser with wavelength of 532 nm was used as laser source. Field emitted scanning electron microscopy, x-ray diffraction, and Raman spectra were applied to characterize the surface morphologies and crystalline structures of the as-deposited ZnO nanorods. Photoluminescence (PL) was carried out to attain the optical properties of the as-deposited ZnO nanorods. It was found that ZnO nanorods have good crystallinity and sound optical properties. Their PL spectra with the strong and sharp ultraviolet peak were observed at room and low temperatures.

Extended photoresponse and multi-band luminescence of ZnO/ZnSe core/shell nanorods

Nanoscale Research Letters (2014)

Qin Yang Hua Cai Zhigao Hu Zhihua Duan Xu Yang

Aligned ZnO/ZnSe core/shell nanorods (NRs) with type-II energy band alignment were fabricated by pulsed laser deposition of ZnSe on the surfaces of hydrothermally grown ZnO NRs. The obtained ZnO/ZnSe core/shell NRs are composed of wurtzite ZnO cores and zinc blende ZnSe shells. The bare ZnO NRs are capable of emitting strong ultraviolet (UV) near band edge (NBE) emission at 325-nm light excitation, while the ZnSe shells greatly suppress the emission from the ZnO cores. High-temperature processing results in an improvement in the structures of the ZnO cores and the ZnSe shells and significant changes in the optical properties of ZnO/ZnSe core/shell NRs. The fabricated ZnO/ZnSe core/shell NRs show optical properties corresponding to the two excitonic band gaps of wurtzite ZnO and zinc blende ZnSe and the effective band gap between the conduction band minimum of ZnO and the valence band maximum ZnSe. An extended photoresponse much wider than those of the constituting ZnO and ZnSe and a multi-band photoluminescence including the UV NBE emission of ZnO and the blue NBE emission of ZnSe are observed.

Extended photo-response of ZnO/CdS core/shell nanorods fabricated by hydrothermal reaction and pulsed laser deposition

Optics Express (2014)

Qin Yang Yanli Li Zhigao Hu Zhihua Duan Peipei Liang

Heterogenous nanostructures shaped with CdS covered ZnO (ZnO/CdS) core/shell nanorods (NRs) are fabricated on indium-tin-oxide by pulsed laser deposition of CdS on hydrothermally grown ZnO NRs and characterized through morphology examination, structure characterization, photoluminescence and optical absorption measurements. Both the ZnO cores and the CdS shells are hexagonal wurtzite in structure. Compared with bare ZnO NRs, the fabricated ZnO/CdS core/shell NRs present an extended photo-response and have optical properties corresponding to the two excitonic band-gaps of ZnO and CdS as well as the effective band-gap formed between the conduction band minimum of ZnO and the valence band maximum of CdS.
