  • Study for the Electrochemical Deposition of ZnO Nanocones on Ti-Ni Substrate and Electrochemiluminescence
    ECS Journal of Solid State Science and Technology, 2014
    Co-Authors: Lei Wang, Xiaoli Zhu, Jifeng Liu
    Abstract:

    In this work, Ti-Ni wire was used as electrode substrate for the electrochemical deposition of ZnO. The Electrochemiluminescence studies demonstrated the excellent electrochemical stability, remarkable electrical conductivity of Ti-Ni wire. The Electrochemiluminescence intensity on per unit projection area for ZnO nanocones deposited on Ti-Ni wire was about four orders of magnitude larger than that from ZnO nanostructures deposited on ITO, the Electrochemiluminescence intensity of per unit surface area of Ti-Ni substrate was almost two orders of magnitude larger than that from ITO substrate. The research presented the stable and sensitive luminescent properties of ZnO nanocones deposited on Ti-Ni substrate, and displayed the potential utility of Ti-Ni material in the development of microelectrodes.

  • Study on Electrochemiluminescence spectra of ZnO flakes.
    Physical chemistry chemical physics : PCCP, 2013
    Co-Authors: Lei Wang, S. Q. Xu, Qiaoli Yue, H.p. Li, Jifeng Liu
    Abstract:

    The Electrochemiluminescence spectra of ZnO were recorded to investigate the surface states of the samples prepared from hydrothermal synthesis and electrochemical deposition, respectively. Photoluminescence spectra and Electrochemiluminescence-potential curves were applied to study the effect of the preparation procedure and particle sizes on the surface electronic structure of products. The results indicated that the preparation conditions and the particle sizes have a small influence on the surface band gap.

  • Study for the electrochemical deposition on single carbon fiber and Electrochemiluminescence of ZnO nanostructures
    CrystEngComm, 2013
    Co-Authors: Lei Wang, Qiaoli Yue, Shuqiu Zhang, Jifeng Liu
    Abstract:

    In this work, ZnO nano-needles were electrochemically deposited onto the surface of single carbon fiber. The influence of deposition condition on the surface morphology of ZnO nanostructures was investigated. A growth mechanism was suggested to elucidate the deposition process. Electrochemiluminescence conducted in 0.1 M KOH solution containing 0.1 M K2S2O8 and 0.1 M KCl displayed the stable and sensitive luminescent property of as-prepared ZnO nano-needles. The Electrochemiluminescence intensity per projection area from ZnO nano-needles deposited on single carbon fiber was almost five orders of magnitude larger than that from ZnO nanostructures deposited on ITO and ZnO dip-coated on ITO. It demonstrated the high Electrochemiluminescence efficiency of ZnO nano-needles deposited on single carbon fiber and the remarkable electrical conductivity of carbon fiber. This work presented a new strategy to deposit oxides on carbon fiber with tunable coverage and nanostructure. Furthermore, the excellent Electrochemiluminescence property of ZnO nano-needles on carbon fiber highlights the importance and potential utility of such nanostructures in the development of optoelectronic and biomedical devices.

  • Detection of 1,3-dihydroxyacetone by tris(2,2'-bipyridine)ruthenium(II) Electrochemiluminescence.
    Analytical and bioanalytical chemistry, 2018
    Co-Authors: Jianrui Sun, Wenyue Gao, Yufeng Song, Pan Hui, Zhongyuan Liu
    Abstract:

    1,3-Dihydroxyacetone, a common cosmetic material and food additive, has been successfully explored as an efficient Electrochemiluminescence coreactant of Ru(bpy)32+ for the first time. It is about 25 times more effective than the well-known coreactant sodium oxalate. The high Electrochemiluminescence efficiency allows sensitive detection of 1,3-dihydroxyacetone without any derivatization. The Electrochemiluminescence method shows two linear Electrochemiluminescence responses over the range of 5.0-500 μM and 500 μM-6.0 mM with a detection limit of 1.79 μM. The proposed method is at least two orders of magnitude more sensitive than other reported methods. Graphical abstract ECL intensity-potential profile of 1,3-dihydroxyacetone (DHA) and oxalate.

    Abstract:

    Sodium dehydroacetate, a common food additive and preservative, is investigated as a co-reactant in efficient Electrochemiluminescence reactions of [Ru(bpy)3]2+ for the first time.

    Abstract:

    Acridines play an important role in various fields of sciences. Besides their application for treatment of a number of infections, cancer, viral and prion diseases, they have been extensively used in chemiluminescence. Electrochemiluminescence (ECL) is a unique kind of chemiluminescence with the precise temporal and spatial control of light emitting reactions by utilizing electrochemistry techniques. These advantages result in increasing attention towards acridines ECL. This review summarizes acridines used in ECL, ECL mechanisms, strategies for increasing ECL intensities, and ECL analytical applications, as well as prospects the future development of acridine ECL.
