要約(英語): Cuprous oxide (Cu2O) films were fabricated on commercially available food wrap and quartz substrate by spin-spray method. Spin-spray method can be used to fabricate oxide films at very low temperatures below 100℃. Cu2O films synthesized at 80℃ on commercial food wraps were single phase confirmed by XRD patterns and Raman spectra. The Raman spectra of Cu2O thin films prepared at 60 and 70℃ on the food wrap showed peaks attributed to copper chloride (CuCl) and copper hydroxide (CuOH). From the surface SEM images, the Cu2O film is composed of small grains. The thickness and grain size of the fabricated films increased with increasing heater temperature. Optical properties, transmittance and reflectance, of the deposited films are low because the films are composed of small grains. The band gaps of all films determined from the transmittance and reflectance were close to those of bulk Cu2O. These results of this experiment show that it is possible to fabricate Cu2O films on inexpensive food wraps, not engineering plastics, using the solution method at low temperature below 100℃.
