摘　　要：掺有铁镍催化剂的石墨棒状阳极和石墨块状阴极之间进行电弧放电，成功制备了单壁碳纳米管。激光拉曼散射和扫描电子显微镜测试表明，单壁碳纳米管直径约1．14m，呈管束形态，管束直径约15～20m。放电过程中的电弧等离子体光谱测试表明其中主要有C2分子的发射峰，光谱分布曲线与普朗克黑体辐射曲线中T=4350K的分布情况吻合，确定放电电弧等离子体温度约4300-4400k，测量误差约100K。Single-shell carbon nanotubes were successfully fabricated by arc discharge with catalysis of Fe/ Ni. The diameter of the carbon nanotubes is almost 1.14 nm and the diameter of carbon nanotubes bundles is almost 15-20 nm according to the measurements of laser Raman scattering and SEM. Arc plume emission spectrum which fits the Planck blackbody radiation function by assuming T= 4 350 K shows Swan band system of C2. The arc plasma temperature is about 4 300--4 400K, and the error is about 100K.
