Abstract The development of one-dimensional nanostructures has revolutionized electronic and photonic industries because of their unique properties. The present paper reports the low-temperature green synthesis of boron carbide nanowires, of diameter 14 nm and length 750 nm, by the condensation method using castor oil as the carbon precursor. The nanowires synthesized exhibit beaded chain morphology, and bandgap energy of 2.08 eV revealed through the Tauc plot analysis. The structure of boron carbide nanowires is revealed by Fourier transform infrared spectroscopy and X-ray diffraction analyses. The photoluminescence study reveals the nanowire's blue light emission capability under ultraviolet excitation, which is substantiated by the CIE plot suggesting its potential in photonic applications.

It is of great interest to synthesize boron carbide nanomaterials and to explore their novel properties. We reported the synthesis of belt-like Si doping boron carbide nanomaterials at a low temperature of 1500C with no catalyst. The structures and formation mechanism were investigated. Broad photoluminescence spectra between 400-500 nm were observed under 380nm light excitation. The mechanism of blue shift of as-received samples in comparison with reported boron carbide nanostructured materials was discussed.
