在不同温度下用化学气相沉积法制备了多壁碳纳米管,并采用扫描电镜和拉曼光谱以及荧光光谱对样品进行了表征。实验结果表明,当反应温度为860℃,有管径为110 nm 均匀的碳纳米管生成,其结构缺陷和非碳管杂质较少,纯度较高。常温下,对3种不同温度下制备的样品的光致发光光谱进行了测量,发现它们的发射波长和发射强度不同,尤其需要指出的是,反应温度为860℃时制备的碳纳米管的发射光谱的光强最强。
The multiwalled carbon nanotubes were synthesized by a chemical vapor deposition under different tempera-tures.The optical properties of the samples were measured by using of the SEM graph,micro-Raman spectra,and fluo-rescence spectra.The experimental results showed that the synthesis of well-distributed carbon nanotubes with less im-purities and defects at the reaction temperature of 860 ℃ was achieved and the carbon nanotubes possessed diameter 110 nm.Different wavelengths and intensities of the samples synthesized under three different temperatures were observed by aids of the photoluminescence (PL)spectra experimentally.In addition,it should be mentioned that luminous intensity at the reaction temperature of 860 ℃ was strongest one.
