Independently detect the spiral phase of cylindrical vector vortex beams

Yanliang He Junmin Liu Zhiqiang Xie Xiaoke Zhang Yao Cai

Although lots of research works have devoted to the generation of cylindrical vector vortex (CVV) beam, little attention has been paid to the detection work. Here, we have experimentally demonstrated a novel detection method to measure the helical topological charge of CVV beams at the working wavelength of 1550nm. The polarization order of CVV beams was firstly measured by using a polarizer. And the topological charge of RHC and LHC were measured by interfering with the plane wave. Then the topological charges of CVV beams were successfully calculated. Experimental results match well with the theoretical prediction and this might provides an efficient measurement technique for detecting the spiral phase of CVV beams.

Carbon nitride prepared through a combined strategy of electrophoresis and vapor deposition

Surface Innovations (2022)

Zhiqiang Xie Yuqing Wang Wei Peng Zhehan Yi Tao Zhang

Photoelectrochemical water splitting converts solar energy into clean hydrogen fuel. In this system, the preparation of high-quality photoanodes is essential for achieving efficient solar hydrolysis. Polymeric carbon nitride has emerged as a promising photocatalyst for solar water splitting due to its visible light absorption, suitable band edge positions and good chemical stability. However, considerable difficulties have been encountered in the preparation of robust and well-bonded carbon nitride films on conductive substrates. Herein, a combined strategy of electrophoresis and vapor deposition results in robust and high-performing carbon nitride film photoelectrodes with good bonding on substrates, suitable thickness for light absorption and enhanced charge separation and transfer abilities. The unique structure of the photoanode thus facilitates the oxidation of water and leads to an optimal photocurrent density of approximately 120 μA/cm 2 at 1.23 V RHE . This work provides new insights for the preparation of polymeric carbon nitride film photoelectrodes, promoting the developments of photoelectric and photoelectrochemical applications based on carbon nitride.

Ni and Fe Dual-Doped Li₄Mn₅O₁₂Spinels as Cathode Materials for High-Voltage Li-Ion Batteries

Journal of The Electrochemical Society (2015)

Zhiqiang Xie Hilary Eikhuemelo Jianqing Zhao Carrington Cain Wangwang Xu

The spinel Li4Mn5O12 has been considered as a prospective 3 V cathode material for the next generation of lithium-ion batteries (LIBs) due to its high energy density and excellent cycling stability. However, the low operating voltage (∼3 V) makes Li4Mn5O12 impractical for high-energy high-power LIBs. To address this issue, Ni and Fe dual doped Li4Mn5-x-yNixFeyO12 has been prepared via a facile sol-gel method combined with post-heat-treatment. The effects of dual-cations doping on the crystal structure, morphology and electrochemical properties were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and galvanostatic charge/discharge analysis. As a result, Li4Mn4Ni0.5Fe0.5O12 exhibits the highest reversible specific capacity of 133 mAh/g at a specific current density of 25 mA/g after 100 cycles and exhibits a significantly improved high voltage performance with corresponding capacity of ∼80 mAh/g at an average voltage of 4.7 V vs. Li/Li+ and ∼122 mAh/g at above 4.0 V. These results indicate the dual doping of Ni and Fe can effectively improve both the operating voltage and reversible specific capacity of Li4Mn5O12 with excellent cycling stability, demonstrating a promising high-voltage cathode material for high-energy high-power LIBs.

Modulation of the photoluminescence of SrTiO₃(001) by means of fluorhydric acid etching combined with Ar⁺ion bombardment

Nanotechnology (2007)

Zheng-hao Li Hai-tong Sun Zhiqiang Xie You-yuan Zhao Ming‐Yen Lu

We report a method to modulate the photoluminescence (PL) of SrTiO3(001) at room temperature by fluorhydric (HF) acid etching and Ar+ ion bombardment. The PL of the virgin sample is in the blue/green range, which can be enhanced in intensity by a factor of 7.2 after being fully etched in HF acid with the peak shape being unchanged. Ar+ ion bombardment of SrTiO3 can blueshift the overall PL, and the peak maximum becomes centred at 403 nm. After fully etching the ion-bombarded sample in HF, the PL peak stays in the blue light range, but its intensity increases to 17.5 times that of the virgin one. Oxygen vacancies assumed to be produced on the lateral sides of SrTiO3 nanograins are responsible for the PL emissions, and their variations in number and nature are attributed to the PL modulation.
