This paper reports a novel method of synthesising CdS nanocrystals (NCs), which 1 octadecene as non coordinating solvent, cadmium acetate and sulfur as Cd and S sources, and myristic acid as surfactant were used respectively. X-ray powder diffraction, dynamic light scattering and scanning electron microscopy revealed that the as-prepared CdS NCs are highly monodispersed and possess a zinc blende crystal structure. The nucleation and growth stages of the NCs could be automatically separated in a homogeneous system with nucleation initiators , tetraethylthiuram disulfide and 2,2 - dithiobisbenzothiazole. To a certain extent, the size of CdS NCs c ould be controlled by altering the quantity of nucleation initiators and the reaction time. The photoluminescence spectra of the CdS NCs with narrow photoluminescence emission peaks are depend ent on the size of the particles.

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.
