Synthesis of Bismuth Pseudocubes by Thermal Decomposition of Bi2Et4

Bismuth pseudocubes were prepared by thermal decomposition of the novel subvalent metal organic precursor tetraethyldibismuthine Bi2Et4 under kinetic control at low temperatures. The pseudocubes were characterized by XRD, SEM, HRTEM, EDX, and SAED, and the influence of the thermolysis temperature an...

Summary:Bismuth pseudocubes were prepared by thermal decomposition of the novel subvalent metal organic precursor tetraethyldibismuthine Bi2Et4 under kinetic control at low temperatures. The pseudocubes were characterized by XRD, SEM, HRTEM, EDX, and SAED, and the influence of the thermolysis temperature and of the capping agents NaN(SiMe3)2 and PVP* on the size- and shape-selective growth of these nanoparticles was investigated.
