Notes:
CdSe nanoparticles with average particles size of ~ 3.4 nm were successfully prepared by thesonochemical reduction of a mixed solution of CdCl2, Na2SeSO3 and CH2CH2OH)2NH at room temperature.CdSe nanoparticles characterized by TEM, XPS and XRD analysis revealed the formation of highpurity cubic phase CdSe nanoparticles with lattice constant of a=6.415Å. CdSe nanoparticles showedrelatively large range of particle size distribution from 20 to 50 nm as the sonication time increased.UV-Vis absorption spectra showed a red-shift in the wavelength region of 545-590 nm as increasingsonication time due to the gradual growth of CdSe nanoparticles in the solution. This paper will mainlypresent the effects of ultrasonic irradiation on the formation and properties of CdSe nanoparticles
