1D-Nano-Scale Porous Silicon (1D-Psi) as Optical Sensor Device

This research article embarks on a thorough experimental inquiry into the detection of kerosene adulteration in petrol, employing a sophisticated one-dimensional microcavity of nano-scale porous silicon (1D-PSMC) sensing device. The significance of this investigation stems from the detrimental consequences of petrol adulteration, which not only aggravates environmental pollution but also jeopardizes the functionality and durability of machinery components, thereby posing significant economic and environmental challenges. The 1D-PSMC, designed to function as an optical sensor device, has undergone extensive scrutiny and practical application. Within this study, we meticulously examine the resonance wavelength shift observed in the reflectance spectra of petrol samples containing various concentrations of kerosene adulterants. Impressively, the sensor device demonstrates outstanding efficacy, capable of detecting adulteration levels as low as 0.5% and even discerning minute variations of 0.01% [Table 1]. This remarkable sensitivity underscores the invaluable potential of the 1D-PSMC sensor in real-world applications. Moreover, the article delves into the intricate relationship between wavelength shifts in the reflectance spectra and the diverse concentrations of kerosene present in the petrol samples. By elucidating these correlations, this research contributes significantly to expanding our comprehension of the operational mechanisms of 1D-PSMC sensing devices in combatting petrol adulteration effectively. Consequently, such advancements hold promises for mitigating environmental degradation and preserving machinery efficiency on a broader scale.
