• Abstract Sensors in recent days have been in great demand in industrial zones of simple, low-cost sensors for effectively sensing various gases. This research work develops electrospinning fibers for optical ammonia sensing based on the wavelength shift. The optical sensing fibers were produced approach by the electrospinning technique. The addition of cellulose acetate (CA) matrix with doped Eosin-Y is an NH 3 fluorophore. The same light emitting diode (LED) light source was used to excite NH 3 -sensitive dyes at 380 nm peak wavelength. Display the eosin Y emission spectrum, with a maximum wavelength of 582 nanometers. The observed red emission wavelength shift and fluorescence intensity at 582 nm decreased with increasing concentrations of NH 3 . The emission spectrum of eosin-Y fluorescence at 582 nanometers is changed with increasing NH 3 concentrations ranging from 0 to 500 parts per million. In this work, according to the experiment results, the sensitivity of NH 3 sensors is 7.73. Finally, the electrospinning fibers for optical NH 3 sensing developed as a result of this research enable effective sensing of NH 3 concentrations in practical applications in a variety of fields, including medical and industrial.
