    Abstract

    Hot-filament chemical vapor deposition (HFCVD) was used to prepare boron-doped nanocrystalline diamond (BDND) nanoflowers on a Cu substrate with a Cu(OH) 2 dendritic architecture that had been formed by using electrostatic self-assembly (ESA) method with nanodiamond particles. The formation of diamond nanoflowers is controlled by the reaction time between the Cu(OH) 2 nanoflowers and the polymeric linker for the electrostatic attachment of nanodiamonds and by the deposition time for CVD diamond growth with a high nucleation density. Through analysis by field emission scanning electron microscopy (FESEM) and Raman spectroscopy, the optimal conditions for the synthesis of BDND nanoflowers are determined, and a possible explanation is provided.
