  • OSA | Highly sensitive photoacoustic multicomponent gas

    A ppb-level photoacoustic multicomponent gas sensor system for sulfur hexafluoride (SF6) decomposition detection was developed by the use of two near-infrared (NIR) diode lasers and an ultraviolet (UV) solid-state laser. A telecommunication fiber amplifier module was used to boost up the excitation optical power from the two NIR lasers. A dual-channel high-Q photoacoustic cell (PAC) wasCited by: 8

  • Highly sensitive and selective sensing properties of

    Gas sensing properties of pristine, defective and heteroatom substituted green phosphorene (GP) monolayers towards SF 6 components such as H 2 S, SO 2, SO 2 F 2, SOF 2 are investigated by using van der Waals corrected density function theory calculations. The adsorptions of H 2 S and SOF 2 on pristine GP are found to be exothermic with weak binding energies (E b) of-0.065 and -0.017 eV

  • A highly sensitive and selective SnS2 monolayer sensor in

    2021-3-1A novel 2D material SnS 2 with an appropriate bandgap and high mobility, has been fabricated successfully and shows promising potential in electronic circuits. However, its applications in gas sensing are still poorly studied. In this work, the sensing behavior of SnS 2 monolayer for SF 6 and its five decomposition gases (SO 2 F 2, SOF 2, H 2 S, HF, and SO 2) is investigated by combining

  • OSA | Highly sensitive gas leak detector based on a quartz

    The implementation, performance validation, and testing of a gas-leak optical sensor based on mid-IR quartz-enhanced photoacoustic (QEPAS) spectroscopic technique is reported. A QEPAS sensor was integrated in a vacuum-sealed test station for mechatronic components. The laser source for the sensor is a quantum cascade laser emitting at 10.56 #x00B5;m, resonant with a strong absorption band of

  • Multivariate Evaluation Method for Screening Optimum Gas

    2020-7-24In previous studies, the selection of optimal gas-sensing materials for detecting target gases mainly relied on their response value, but other indices, such as the recovery capability of materials, have usually been overlooked. Here, we propose a new method for evaluating sensor effectiveness that includes a broader range of performance indices. In this study, four gas sensors based on metal
