Zn- doped SnO2 nanocrystallites were prepared by taking SnCl4.5H2O as precursor, using water as a solvent via sol-gel process. X-ray diffraction (XRD), Fourier transform infrared spectra (FTIR),Thermal gravimmetry spectrometry (TGA),Scanning electron microscopy (SEM),Transmission electron microscopy (TEM), Energy Dispersive X-ray analysis (EDX), UV-Vis spectroscopy and Photoluminescence (PL) were used to analyzed the crystal structure, particle size, molecular structures and optical properties of the prepared SnO2 nanoparticles. The XRD pattern revealed that the tetragonal rutile phase and the average crystallites size were calculated to be 10 nm for Zn-doped SnO2 nanoparticles calcined at 600ºC. The spherical-like morphology of the as-synthesized Zn-doped SnO2 nanoparticles was observed in the SEM and TEM studies. Zn-doped SnO2 nanoparticles were exhibit enhanced UV emission at ~ 394 nm and could be used as nanoscale optoelectronic devices..

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.
