✦ Synopsis

Large polysilane spherulites have been observed. The spherulites were prepared by controlling the removal rate of solvents from poly(n-butyl-n-pentylsilane)

under a xylene atmosphere. The diameter of the spherulites was greater than 0.1 mm. The structure of the spherulites was compared with that of the polysilane powder by polarized microscopy, SEM, DSC, and x-ray diffractometry. A high photoluminescence quantum yield of 0.3 was obtained for the spherulites. c 1997 ,JohnWiley & Sons, Inc.

particles serve as the catalyst and direct the growth of boron nanowires via a vaporΒ±liquidΒ±solid (VLS) mechanism. In our experiments, however, no catalyst was used and no metal nanoparticle can be found at the tip of both stem and branches or at the junction region using TEM and SEM. We suggest tha
