我们报告了一种新的飞秒时间分辨荧光光谱仪，使我们能够在一次测量中观察荧光强度作为时间波长的二维图像。该方法利用了时间-空间转换技术和荧光和频率混合与飞秒门脉冲。它提供的荧光图像分别覆盖约2ps和约60nm的时间和光谱范围。校正的时间和强度轴的图像是由使用长寿命的染料荧光。所获得的β -胡萝卜素二维荧光图像显示了该方法在超快激发态动力学定量研究中的巨大潜力。
We report a new femtosecond time-resolved fluorescence spectrometer that enables us to observe fluorescence intensity as a time-wavelength two-dimensional image in a single measurement. This method utilizes a time-to-space conversion technique and fluorescence sum-frequency mixing with a femtosecond gate pulse. It provides a fluorescence image covering temporal and spectral spans of approximately 2 ps and approximately 60 nm, respectively. Calibration of the time and intensity axes of the image is made by use of a long-lived dye fluorescence. The two-dimensional fluorescence image of beta-carotene obtained demonstrates the high potential of this method for quantitative studies of ultrafast excited-state dynamics.
