Document Abstract
In this paper, we have presented a basic analysis of Zinc Oxide (ZnO) Quantum Dot Gas Sensor. We have studied the synthesis of Zinc Oxide (ZnO) quantum dots embedded in polyvinylpyrrolidone (PVP) and polyvinyl alcohol (PVA) matrix. The sensor response has been measured for different pollutant gases including acetone (C3H6O) and ethanol (C2H5OH) for different concentrations in the 100ppm-500ppm range. We have studied sensitivity and transient characteristics of Acetone(C3H6O) and Ethanol (C2H6) reducing vapors via Zinc Oxide (ZnO) Quantum Dot Gas Sensor embedded in PVP and PVA matrix. The samples have been prepared via quenching technique where bulk Zinc Oxide (ZnO) powder is calcined at a very high temperature of 1200˚C and then quenched into ice cold polyvinylpyrrolidone solution. For the synthesis of Zinc Oxide (ZnO) Quantum Dot embedded in PVA matrix, we use Zinc Oxide (ZnO) powder is calcined at very high temperature of 1000⁰C and then quenched into ice cold polyvinyl alcohol (PVA) solution. We have studied this sample’s specimen characteristics by using Optical analysis such as UV–VIS spectroscopy, which ranged from the ultraviolet (UV) region to the near-infrared (NIR) region.
