瞬态吸收（TA）光谱已广泛应用于各种材料和分子的激发态动力学研究。从 TA 光谱学到 TA 显微镜的转变，可以实现 TA 的空间分辨测量，正在开启新的研究，以更全面地了解功能材料中的激发态动力学，以及绘制用于精确诊断的关键生物色素的图谱。在这里，我们回顾了最近突破空间分辨率、检测灵敏度和成像速度极限的仪器进展。我们进一步强调材料科学和生命科学中的新兴应用。
Transient absorption (TA) spectroscopy has been extensively used in the study of excited state dynamics of various materials and molecules. The transition from TA spectroscopy to TA microscopy, which enables the space-resolved measurement of TA, is opening new investigations toward a more complete picture of excited state dynamics in functional materials, as well as the mapping of crucial biopigments for precision diagnosis. Here, we review the recent instrumental advancement that is pushing the limit of spatial resolution, detection sensitivity, and imaging speed. We further highlight the emerging application in materials science and life science.
