Laser irradiated gas sensors: A review

Abstract

Further modernization of our life is linked with emission of more toxic gases and vapors. Hence, for high standards of today's life, development of more sensitive and selective gas sensors is vital in various sections. Irradiation with high energy beams such as laser is a promising way to boost sensing performance of resistive gas sensors. Laser irradiation not only is a cheap and available energy, but also highly effective for modification of electronic properties through generation of defects and increasing of surface roughness. Herein, we have thoughtfully discussed the effect of laser irradiation on the sensing performance of gas sensors. All in all, laser irradiation is a highly efficient strategy to boost overall quality of gas sensors. However, optimization of laser irradiation conditions is necessary to achieve the highest sensing performance.
