摘要：

The present paper reports the various physico-chemical properties of MgO film obtained by using a precursor prepared by sol-gel technique. The aim of this work is to produce films with nano size particles so as to employ them for sensor applications, as adsorption in such films increases many folds due to increase in surface area. Infra-red spectroscopic and thermal studies indicate the presence of solvent in the precursor, which perhaps helps in decomposition to nano-particles during the nucleation of the film. The films have been deposited on the glass rod bend in U-shape for humidity sensor. The results as obtained are encouraging to use MgO film as humidity sensor. (C) 2003 Elsevier B.V.
