Diverse BNO-NPs were obtained while utilizing different precursors, gas flow rates and synthesis temperatures in the range of 1200-1430 °C. The BNO-NP morphologies, atomic structures and spatially-resolved chemical compositions were studied by scanning (SEM) and transmission electron microscopy (TEM), X-ray diffraction (XRD), energy-dispersive X-ray, Fourier-transform infrared and confocal Raman spectroscopy. Particle size distributions were measured using dynamic light scattering under visual microscopic control. A growth model of different spherical BNO-NP types based on the detailed analysis of physical-chemical processes at different BOCVD stages was proposed. A new type of spherical BNO-NPs of "hedgehog" morphologies with BN nanowires on their surfaces was first predicted in accordance with the designed model and then experimentally verified. © 2016 The Royal Society of Chemistry. %G English %L hal-02184718 %U https://normandie-univ.hal.science/hal-02184718 %~ CEA %~ CNRS %~ INSA-ROUEN %~ COMUE-NORMANDIE %~ INC-CNRS %~ UNIROUEN %~ ENSICAEN %~ UNICAEN %~ CRISMAT %~ INSA-GROUPE %~ TEST2-HALCNRS
