Ultra long SiC core and SiO2 shell nanocables have been prepared by pyrolysis of poly(dimethyl siloxane) at 1050 degrees C in flowing Argon. The longest nanocable can be up to at least 6 mm. Transmission electron microscopy observations indicate that the diameter of the cores varies from about 3 to 18 nm, and the thickness of the outer sheaths varies from about 6 to 45 nm and that the cores are crystalline and the sheaths are amorphous. The growth of the nanocables may be governed by a chemical vapor solid process. The nanocables exhibit good photoluminescence property.
通过在流动的氩气中于1050℃下热解聚二甲基硅氧烷制备了超长的碳化硅芯和二氧化硅壳纳米电缆。最长的纳米电缆可达至少6毫米。透射电子显微镜观察表明，芯的直径在约3至18纳米之间变化，外鞘的厚度在约6至45纳米之间变化，并且芯是结晶的而鞘是非晶的。纳米电缆的生长可能受化学气相固相过程控制。这些纳米电缆表现出良好的光致发光特性。
