Patent ID: 7678413

Claim:
A sol-gel process for the preparation of monoclinic CeTi 2 O 6 thin film form, the said process comprising the steps of: a) preparing an alcoholic solution of about 0.20-0.25 M cerium chloride heptahydrate in absolute ethanol, b) adding the solution prepared in step a) to titanium propoxide having concentration in the solution in the range of 0.331-0.624 M, followed by stirring for a period of 4-10 min and aging at 20-30° C. for a period of about one week, wherein the Ce:Ti mole ratio used is in the range of 0.4:1 to 0.6:1, c) spin coating the above said aged solution on electrically conducting substrate or micro slide glass, followed by air drying for a period of about 10-20 min. and annealing the film in air, at a temperature in the range of 580-620° C. for a period of 5-10 min. to obtain the desired monoclinic CeTi 2 O 6 thin film.
