Time gated Fourier transform spectroscopy with burst excitation for time-resolved spectral maps from the nano- to millisecond range

Abstract

We demonstrate burst-mode Time Gated Fourier Transform Spectroscopy (bmTG-FTS), a technique for simultaneously capturing and disentangling emission signals from short- (ns) and long-lived (μs–ms) states. We showcase the possibilities of the technique by preparing time gated temporal-spectral maps from a dual-emissive DNA-stabilized silver nanocluster (DNA-AgNC).
