Abstract
Cuprous oxide (Cu2O) thin films have been deposited on stainless steel substrates through potentiostatic electrodeposition technique. The structure and morphology of these films were characterized by X-ray diffraction and Scanning electron microscopy. The change in hkl plane orientation intensity was observed for thin films deposited at different bath pH. The effect of bath temperature on crystallite size were studied. The optical properties of thin films were analyzed by using UV–Visible spectroscopy. The change in band gap with bath pH have been investigated. From Raman spectroscopy only single phase Cu2O peaks have been observed. The current of Cu2O thin films changes with scan rate and concentration of glucose. For 4 mM glucose the maximum current was observed. The results shows that the sensitivity of Cu2O thin films increases with concentration of glucose. Finally, Cu2O thin films shows high glucose sensing at room temperature.
