Circumventing Inner Filter Effects in Ultrafast Near-Infrared II (NIR-II) Up-Conversion Spectroscopy Using Front-Face Optical Configuration

Abstract Self-absorption is fatal in up-conversion ultrafast spectroscopy, severely suppressing the fluorescent signal. To conquer this problem, we implemented a front-face optical configuration in fluorescence up-conversion spectroscopy to accurately record the intrinsic excited...
