  LIBS技术因其能够快速、实时、原位、全元素分析等优点而受到广泛关注。然而,光谱分析过程中存在的谱线干扰、自吸收效应和基体效应等因素一直影响着其定性、定量分析功能,使得LIBS仪器难于实现真正应用。针对这一现状,本团队开展了以下方向研究:

  (1)理论研究:主要研究激光诱导等离子体发射光谱增强、光谱干扰、自吸收和基体效应问题的解决,进一步改善LIBS定量分析精准度、灵敏度和重复性;

  (2)应用研究:致力于推动激光探针快速检测在工业、农业、环保和食品安全等方面的研究,主要包括金属、矿石、土壤、塑料、液体和生物成分的快速检测;

  (3)仪器化研究:研究开发系列LIBS仪器设备,开发LIBS光谱分析软件。
