Abstract: Cu doped SnO2 were prepared via low cost and simple Chemical Precipitation Method for optical ethanol sensing. Morphology, structure and optical properties were characterized by Scanning Electron Microscope (SEM), Energy Dispersive X-ray Spectroscopy (EDS), X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and Ultraviolet Visible Spectroscopy (UVS). 3 wt% of Cu is present in SnO2 confirm by EDX, Cu doping does not affect the structure of SnO2 and also decreases the size of SnO2 confirm by the XRD, the average size of Cu doped SnO2 was found 6.97 nm. Light Transmittance and absorbance of the material are high, that means it has optical property. Cu doped SnO2 exhibit good sensitivity towards ethanol sensing. The average ethanol sensitivity was found to be 0.31 μW / ppm.
