ZnS nano material s are synthesize d by arc discharge with ZnS powder as r aw materials. The sample is characterized by X ray Diffraction, scanning electron microscopy, transmission electron microscopy. A lot of ZnS nanorods and nanoparticles are found in the sample. The ZnS nanorods with the diameters of 20 40nm and the lengths of 100 250nm exhibit single crystals with hexagonal wurtzite structure, and the growth process of ZnS nanorods can be interpreted by the vapor solid mechanism. Photol uminescence (PL) spectrum shows a blue emission at around 410nm and a green emission at a round 520nm. A phenomenon of sulfur loss of ZnS nanostructures is observed which can be interpreted by the process of carbon thermal reduction and pyrolysis of ZnS. Sulfur loss can be resolved by adding abundant S in raw materials.

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.
