Abstract: The preparation of Zinc Oxide thin film with dip coating of gas sensing methods are we discuss in this paper .For sol gel preparation the researcher using Zinc Nitrate hexahydrate (Zn (NO3)2 .6 H2o) and organic polymer sodium carboxyl methyl cellulose (Na-CMC) as basic material from the size of the prepared thin film varied by XRD, morphology was studied by (FE-SEM) and the gas sensing was studied using acetaldehyde has been tested. The gas sensor parameter such as response selectivity, response/recovery time towards NO 2 was reported.
Keywords: ZNO, Na-CMC, Sol- Gel Dip Coating, Thin Film, NO2 Sensors.
Scope of the Article: Innovative Sensing Cloud and Systems
