摘　　要：金属锌的探测工作对于诸多领域有着重要意义。本研究采用激光诱导击穿光谱技术对锌进行了检测分析,标记出锌在200~895 nm波段内的31条特征谱线。并且在不同激光能量下进行了多次探测,发现激光能量对于锌谱线的相对强度影响显著。同时计算了不同激光能量下的等离子体温度,发现等离子体温度随着激光能量的增加而逐渐升高。此外,研究了离子线与原子线强度比和等离子体温度的关系,结果表明,锌的离子线与原子线强度比和等离子体温度之间呈正相关趋势。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.
