Abstract
Periodically twinned SiC nanowires and smooth SiC nanowires were largely synthesized by the sol-gel and the carbothermal reduction method, in which tetraethoxysilane and biphenyl were employed as silica and carbon precursors, iron nitrate and cobalt nitrate used respectively as additives. XRD, SEM, PL and VNA were used to characterize the SiC samples. The results show that the samples are silicon carbide nanowires with different morphology. Periodically twinned SiC nanowires and smooth SiC nanowires have different photoluminescence properties. Periodically twinned SiC nanowires exhibited excellent microwave absorption properties..
