This paper reports the effect of Sn doping on structural and optical properties of CuO nanoparticles prepared by the simple hydrothermal method in mild condition without pH adjustment and surfactant. The structural and optical properties of these CuO and Sn doped CuO particles were investigated using X-ray powder diffraction (XRD), Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and photoluminescence spectroscopy (PL). powder X-ray analysis reveals that Sn+4 ion have substituted the Cu+2 ions without changing the monoclinic structure of CuO but the average particle size of nano CuO increases from 16 nm to 22 nm.The PL emission spectra revealed blue shift after introducing Sn into the CuO and an intensity decreasing as well.
