08 - 284Synthesis of Monodisperse Nanoparticles of Barium Titanate: To-ward a Generalized Strategy of Oxide Nanoparticle Synthesis. —Monodisperse nanoparticles of BaTiO3 with diameters ranging from 6 to 12 nmare synthesized from BaTi(OOCC7H15)(OiPr)5 by a combined injection–hydrolysis method (injection of the precursor into a mixture of diphenyl etherand oleic acid as stabilizing agent at 140 ◦C, followed by hydrolysis usinga 30 wt.% H2O2 solution). The samples are characterized by TEM andXRD. It is suggested that the synthesis procedure offers the possibility of ageneralized approach to the production of single and complex oxide nanopar-ticles with size tunability and solution mobility. — (O’BRIEN, STEPHEN;BRUS, LOUIS; MURRAY, CHRISTOPHER B.; J.
