摘要：

Cobalt oxide (Co3O4) films prepared by pyrolysis of an organometallic precursor show a humidity-sensitive absorbance change in the visible wavelength region at room temperature. The light absorbance change is strongest at wavelengths around 350-400 nm. The reversible absorbance change and the relatively fast response time (within a few minutes) make the Co3O4 film a potential candidate for optical humidity detection.
