Abstract

Citric acid (Cit)-coordinated and Eu3+-doped calcium phosphate nanoparticle dispersions were successfully transformed into a gel-like aggregation upon heating near physiological temperature. This phenomenon would be attributed to the formation of interparticle interactions among the Cit coordination layers and Ca2+ ions on the nanoparticle surfaces.
