摘要：

We investigated a gas sensor that makes use of the surface plasmon resonance (SPR) effect in a thick layer of gold (Au), copper (Cu), ZnO, and multilayer black phosphorous (BP). The suitability of the proposed gas sensor was investigated for a range of analyte gases recognized for their toxicity, greenhouse effect, or flammability. The proposed gas sensor obtains a maximum sensitivity of 258.77 degrees/RIU with a remarkable full width at half maximum (FWHM) of 7.12 degrees, detection accuracy (DA) of 0.14/degrees, and Figure of merit (FoM) of 36.22. The result of our enhanced numerical analysis indicates that the performance of a multilayer BP is enhanced when compared to a conventional gas sensor. As a result, using a SiO2 prism to sense different gases at a wavelength of 633nm, the suggested gas sensor may be more advantageous. Moreover, the maximum sensitivity of 374.31/RIU is obtained with a remarkable DA of 0.11 degrees and FoM of 37.63/RIU to detect NO2 gas sensing to maintain the Rminvalue. The gas sensor performance is high at different refractive indices for gas analyte (1-1.07). The performance of the proposed gas sensor is superior to that of the existing gas sensors.
