Abstract: Acidic gases are highly toxic for humans, wild animals and environment. Therefore, the development of easy-to-use, low cost, fluorescent paper-based rapid and selective sensing of acidic gas in open as well as closed environments is of great significance. In the present work, we have synthesized red emissive sulfur using a two-step oxidation process and infused it into standard filter paper for the detection of acidic fumes. The as-prepared red emissive fluorescent paper exhibits significant change in emission color from red to dark brown upon exposure to acidic vapors. Therefore, the simple, portable and disposable analytical fluorescent paper-based sensing platform can be used as a next generation alternative technique for the effective detection of acidic gases with numerous applications in food quality control, clinical determination and environment surveilling. © 2021 IEEE.
