英文摘要Laser-micro confocal Raman spectroscopy is widely used to study molecular structure, bonding effects. loading, and bternal stress. The signal intensity and quality of Raman spectra are particularly important for the analysis. However. Raman Maser irradiation the surface of sensitive samples produces thermal effects and, thus structural damage. The damaged parts of the sample collapse and shine. To obtain high quality Raman spectra and realize non destructive characterization, this paper novatively proposes adding KBr as heat sink to climinate the thermal effect of laser. A series of carbon materials that are Jasily damaged under laser radiation were selected as the research objects and the relationships between the carbon content of the samples, the addition of KBr. and the Raman spectral parameters and signal intensity were explored, The experimental Fesults show that adding KBr can effectively inhibit the sensitive samples from being damaged by the Raman laser. When the ddition ratio of KBr is 12. accurate and nondestructive Raman spectroscopic detection of this material can be realized. In Addition, the graphitization R values of carbon materials detected in different microregions are very close to each other, with the nerease of carbon content, the position of the D peak is shifted to the low-wave region by 3 cm(-1) and the position of the G peak in shifted to the high wave region by 2 cm(-1) increased with a decrease the intensity ratio and the difference between the peak positions of the D peak and the G peak and an increase in the ordering of the samples.
