| Abstract: | By using a simple and low-cost arc-discharge method in deionized water,high purity SiC/SiOx nanocables have been synthesized in large-scale.The synthesized SiC/SiOx nanocables consist of an uniform cubicβ-SiC core and an amorphous silicon oxide shell. They are about several hundrednanometres to several microns in length and the smallest average diameter of theβ-SiC core is only about 5 nm, which may be attributed to the arc-dischargein deionized water approach and to the constraint of the outer sheath. Thediameters of the as-grown nanocables can be controlled through adjusting theprocessing parameters. The SiC/SiOx nanocables emit stable violet-blue light atwavelengths of about 315 nm and 360–400 nm. Compared to the reported results inβ-SiC nanowires or nanocables, the photoluminescence of the synthesized nanocablesshows significant blueshift, which is resulted from the small diameter of theβ-SiC core. The photoluminescence intensity can be enhanced by annealing the as-preparedSiC/SiOx nanocables. [ABSTRACT FROM AUTHOR] |
