Uniform-sized and well-crystalline Eu3+ doped Y2O3 nanocrystals (NCs) have been successfully synthesized via a metal-oleate decomposition method using 1-octadecene as high boiling organic solvents. X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR), photoluminescence (PL) and the kinetic decay were employed to characterize the samples. It was found that Y2O3:Eu3+ nanocrystals can be indexed to cubic Y2O3 phase with high purity. The FE-SEM and TEM images reveal that the as-prepared Y2O3:Eu3+ consists of uniform nanospheres with the mean particle size of 19 nm in a relatively narrow size distribution. The Y2O3:Eu3+ nanocrystals exhibit strong luminescence upon ultraviolet excitation, suggesting its potential application in the fields of color displays and bioimaging.

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.
