Abstract
Metal organic precursor compounds are dissolved in an organic solvent to form a nonaqueous liquid precursor. The liquid precursor is applied to the inner envelope surface of a fluorescent lamp and heated to form a metal oxide thin film layer. The metal oxide thin film layer may be a conductor, a protective layer or provide other functions. The films have a thickness of from 20 nm to 500 nm. A conductive layer comprising tin-antimony oxide with niobium dopant may be fabricated to have a differential resistivity profile by selecting a combination of precursor composition and annealing temperatures.
