SiC nanowires in large quantities: Synthesis, band gap characterization, and photoluminescence properties

Effective Synthesis of Silicon Carbide Nanotubes by Microwave Heating of Blended Silicon Dioxide and Multi-Walled Carbon Nanotube

“…This is due to the presence of SiO 2 which was remained unreacted because of insufficient MWCNTs in the mixture. Similar result was also reported by Chiu and Li 32 , they reported that there was an emission peak centered at 390 nm which was attributed to the oxygen discrepancy in SiO 2 particles and thus indicated the presence of SiO 2 particles after the synthesis of SiC.…”

Effect of Heating Duration on the Synthesis of Silicon Carbide Nanotubes by Microwave Heating of MWCNTs and Silica

“…This result shows good consistency with the XRD pattern in Figure 2(a). Chiu and Li (2009) also reported the similar result in which the PL peak corresponded to SiO 2 particles was observed centred at 390 nm in PL spectrum and indicated the oxygen discrepancy of the SiO 2 particles and showed that some SiO 2 particles not reacted with carbon to form SiC nanowires. Meanwhile, it can be observed that only PL peak corresponding to single-phase β-SiC was detected at wavelength of 465 nm in the PL spectra of SiCNTs synthesized at 40 and 60 min as shown in Figure 5 Figure 6 shows the FTIR spectra of SiCNTs synthesized at 20, 40 and 60 min.…”

A simple catalyst-free route for large-scale synthesis of SiC nanowires

“…Motivated by these applications of 1D SiC nanomaterials, a variety of techniques have been reported for the synthesis of SiC nanowires, including chemical vapor deposition [13,14], thermal evaporation [15,16], carbothermal reduction [17,18], laser ablation [19], arc-discharge [20], carbon nanotubes confined reaction [21,22], and catalyst-assisted [23,24]. In most of these methods, expensive raw materials, catalysts, and sophisticated techniques were used.…”
