Reversible regulation of CdTe quantum dots fluorescence intensity based on Prussian blue with high anti-fatigue performance

Abstract

A fluorescence switching device with excellent anti-fatigue performance based on the electrochromic material Prussian blue and fluorophore CdTe quantum dots was realized. The fluorescence switching device ultimately demonstrated a high fluorescence contrast, short response time and superior anti-fatigue property. Notably, the fluorescence contrast remains unchanged after 133 cycles.
