    Jun 01, 1998  The most remarkable feature of the precursors is that they allow the attainment of bismuth mixed oxides in much softer conditions than the traditional ceramic method where Ca 4 Bi 6 O 13 and Sr 2 Bi 2 O 5 are obtained at 850°C for 48 h and BaBiO 3 at 800°C for 48 h. The thermal treatment of the described precursors allows the synthesis of ...

    Development of a Novel Bismuth Precursor for MOCVD

    preparation by MOCVD using several bismuth precursors, for example BiMe3, triarylbismuth [BiPh3 and Bi(o-Tol)3] and trialkoxidebismuth [Bi(OtBu) 3and Bi(mmp)3]. Among these bismuth precursors, only BiMe3 is a liquid at room temperature. Liquid precursors are of great advantage for MOCVD process from the viewpoint of the material delivery system.

    The development of cost-effective, functional materials that can be efficiently used for sustainable energy generation is highly desirable. Herein, a new molecular precursor of bismuth (tris(selenobenzoato)bismuth(III), [Bi(SeOCPh)3]), has been used to prepare selectively Bi or Bi2Se3 nanosheets via a colloidal route by the judicious control of the reaction parameters.

    Dec 20, 2004  Bismuth titanate was synthesized under hydrothermal conditions from an amorphous bismuth–titanium precursor gel. The gel was formed by mixing a bismuth acetate complex with titanium butoxide and then adding the solution dropwise into 6M NaOH. The resulting gel suspension was reacted under hydrothermal conditions at temperatures ranging from 160° to 200°C to form crystalline bismuth titanate.
