锌的激光诱导击穿光谱与等离子体温度研究
Investigation of laser-induced breakdown spectroscopy and plasma temperature of zinc
摘要
Abstract
The detection of metallic zinc(Zn)is of great significance in many fields.In this study,the laser-induced breakdown spectroscopy technique is used to detect Zn,and 31 characteristic spectral lines of Zn in the region of 200-895 nm are identified.Moreover,several detections are carried out under different laser energy,and it is found that laser energy has a great influence on the relative intensity of Zn spectral lines.At the same time,the plasma temperature under different laser energy is calculated,and the results indicate that the plasma temperature increases gradually with the increase of laser energy.In addition,the relationship between the ratio of ion line intensity to atomic line intensity and plasma temperature is investigated,and the results show that there is a positive correlation between the ratio of ion line intensity to atomic line intensity and plasma temperature of Zn.关键词
