| Research Abstract |
A new technique for preparing aluminum films having large surface areas and models for functional devices such as electrolytic capacitors or catalysts by vacuum evaporation was developed. The evaporation of aluminum onto heated aluminum substrates at temperatures between 460 and 520 degrees C gave the aluminum films having an isolated and columnar microstructure of standing grains with a diameter of about 1 micrometer. The comparison between the electric double-layer capacities of the aluminum films having the microstructure and the smooth aluminum substrates obtained from AC impedance measurements showed about a 2.6 times increase in the surface area. Concentrations of ethanol in gasoline were measured using an aluminum-deposited surface plasmon resonance-based glass rod sensor. The sensor has the evaporated aluminum film with a thickness of 15 nm and with a light-emitting diode at a wavelength of 400 nm and a photodiode.
