Nanoparticles of undoped and Mn doped CdS (Cd1-xMnXS; x=0.01) were synthesized by co-precipitation method.X-Ray diffraction (XRD) studies reveal that CdS crystallized in Cubic (Zinc blende) phase.Field Emission Scanning Electron Microscopy (FESEM) study reveals that the undoped nanopowders are formed into aggregates while doped particles are in spherical shape. The nanoparticles were characterized using UV-Visible (UV-Vis) and Fourier Transform Infra Red (FTIR) studies. The band gap of the doped CdS is more than the undoped and this is due to quantum size effect of the nanoparticles. The average crystallite size of the doped and the undoped CdS nanoparticles is 1.58nm and 1.95 nm respectively. The photoluminescence spectrum of the Mn doped CdS show the blue band emission and green emission..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
