ZnSe nanosheets have been fabricated by femtosecond laser ablation in distilled water at room temperature. Their crystal structure, crystal phase, shape and size distribution, a nd photophysical property are investigated using X ray diffraction (XRD), R aman spectroscopy, field emission scanning electron microscopy (FE SEM), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM) and UV Vis spectroscopy. The as prepared ZnSe nanosheets efficiently catalyze the phot odegradation of methyl orange (MO) present in aqueous solutions under visible light irradiation, exhibiting higher photocatalytic activity than ZnSe microsized particles. The high photoactivity of the nanosheets can be attributed to the combined effects of large surface areas and the more unsaturated surface coordination sites exposed to the solution..

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.
