Abstract
Initial film layers prepared from tin(II) chloride spontaneously generate open cavities when the initial film layers are thermally cured to about 400° C. using a temperature ramp of 1° C./minute to 10° C./minute while exposed to air. The openings of the bowl-shaped cavities have characteristic dimensions whose lengths are in a range of 30 nm to 300 nm in the plane of the top surfaces of the cured film layers. The cured film layers comprise tin oxide and have utility in gas sensors, electrodes, photocells, and solar cells.
