摘要
本研究调查了样品温度 Ts 对真空和空气中激光诱导击穿光谱（LIBS）发射特性和免校准 LIBS（CF-LIBS）定量分析的影响。我们使用铝锡铜合金分析了 20 °C 至 170 °C 温度范围内的光谱线。评估包括发射线强度、等离子参数、膨胀图像和激光烧蚀坑形态。CF-LIBS 分析结果表明，即使对于线较弱的次要元素，升高的 Ts 也能保持定量的准确性。在大气条件下，锡会发生偏析，但 CF-LIBS 仍然保持稳定。这些结果凸显了 CF-LIBS 通过减轻 Ts 引起的影响而实现各种应用的潜力。
Analysis of an Al-Sn-Cu alloy by calibration-free laser-induced breakdown spectroscopy under varying sample temperature conditions
This study investigates the impact of sample temperature Ts on Laser-Induced Breakdown Spectroscopy (LIBS) emission characteristics and Calibration-Free LIBS (CF-LIBS) quantitative analysis in vacuum and air. Using an aluminum‑tin‑copper alloy, we analyze spectral lines within a 20 °C to 170 °C temperature range. Evaluation encompasses emission line intensities, plasma parameters, expansion imagery, and laser ablation crater morphologies. CF-LIBS analysis underlines that elevated Ts maintains quantitative accuracy even for minor elements with weak lines. In atmospheric conditions, tin segregation occurs, yet CF-LIBS remains robust. These results highlight CF-LIBS's potential for varied applications by mitigating Ts-induced effects.
