YVO4 nanocrystals doped with Eu (5 at.%) or Gd (1 at.%) were synthesized by precipitation method and annealed at various temperatures between 60ºC and 900ºC. The average size (coherence domain) of the YVO4 and nanocrystals, estimated from X-ray diffraction measurements, varies from ~7 nm to ~60 nm, function of the annealing temperature. The morphological transformations produced by thermal treatments in YVO4 nanocrystals were monitored using optical spectroscopy with Eu3+ as probe and EPR spectroscopy, the paramagnetic probe being Gd3+..

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.
