Cd1-xMnxS (x = 0, 0.1, 0.2) nanoparticles, prepared by co-precipitation method under ultrasonic irradiation, were studied by means of X-ray diffraction, scanning electron microscopy, FTIR and UV-Vis  spectroscopy measurements. The average particle size of nanoparticles from the scanning electron microscopy image is about 20-30 nm. Results show that partial substitution of Cd by Mn leads to a reduction in lattice parameters and enhancement of band gap energy. This is attributed to the nanometric grain size and quantum confinement effects. The particle size is calculated to be around 2 nm that is almost in agreement with the crystallite size estimated from the XRD result.
