用掺钕钇铝石榴石（Nd：YAG）激光器的单脉冲辐照多壁碳纳米管（MWCNT）薄膜表面。当用23.7mJ/cm 2的脉冲Nd：YAG激光照射MWCNT膜时，计算的最大表面温度变为304 °C。随着激光功率从59.4 mJ/cm 2增加到469 mJ/cm 2，表面温度从595 ° C增加到2968 °C。通过增加两个特征性拉曼位移ID（缺陷诱导模式：D带）和IG（石墨诱导模式：G带）的强度来检查MWCNT膜，以澄清脉冲Nd：YAG激光加热的效果。此外，一个新的原始图像分析方法，开发了表征碳纳米管的扫描电子显微镜（SEM）图像。该方法可用于测量生长态和脉冲Nd：YAG激光退火后碳纳米管的直径。检测到的直径在40和60 nm之间的数量随着激光能量密度从181 mJ/cm 2增加到268 mJ/cm 2而增加。
A multiwalled carbon nanotube (MWCNT) film surface was irradiated with a single pulse from a neodymium-doped yttrium aluminum garnet (Nd:YAG) laser. When an MWCNT film is irradiated with a pulsed Nd:YAG laser of 23.7 mJ/cm2, the calculated maximum surface temperature becomes 304 °C. The surface temperature increases from 595 to 2968 °C with an increase in laser power from 59.4 to 469 mJ/cm2. The MWCNT film is examined by increasing the intensity of the two characteristic Raman shifts ID (defect-induced mode: D-band) and IG (graphite-induced mode: G-band) to clarify the effect of pulsed Nd:YAG laser heating. Moreover, a new original image analytical method is developed to characterize CNTs from scanning electron microscopy (SEM) images. This method is useful for measuring the diameter of as-grown CNTs and those after annealing with a pulsed Nd:YAG laser. The number of detected diameters between 40 and 60 nm increases with an increase in laser energy density from 181 to 268 mJ/cm2.
