We show a femtosecond fluorescence upconversion setup with broadband detection to measure time-resolved emission spectra in the 300-550 nm range, upon excitation between 250 and 300 nm, with a time resolution of 100 fs. We present time-resolved fluorescence emission spectra of 2,5-diphenyloxazole in solution, which demonstrate the capabilities of the setup.
我们展示了一种具有宽带检测功能的飞秒荧光上转换装置，用于测量在250至300纳米之间激发时，300 - 550纳米范围内的时间分辨发射光谱，时间分辨率为100飞秒。我们给出了溶液中2,5 - 二苯基恶唑的时间分辨荧光发射光谱，展示了该装置的性能。
