Preparation and characterization of monodispersed spherical Eu2O3 ultrafine particles testting

摘要

Monodispersed spherical Eu2O3 ultrafine particles were successfully prepared by calcinating the precusor precipitate Eu(OH)CO3. H2O particles obtained by aging a Eu(NO3)(3) solution in the presence of urea. The effect of various reaction conditions such as the concentration of urea and Eu(NO3)(3), and the pH on the resulting particles was investigated and the optimal preparation conditions were obtained. XRD, IR, TG, TEM and specific surface area measurement techniques were used to characterize the obtained samples.
