The amplification of light in NIR-II from Ag 2 S QDs via metal enhanced fluorescence (MEF) is reported for the first time. Significant fluorescence enhancement of over 100 times for Ag 2 S QDs deposited on Au-nanostructured arrays, paves the way for novel sensing and imaging applications based on Ag 2 S QDs, with improved detection sensitivity and contrast enhancement. Metal enhanced fluorescence (MEF) allows up to two orders of magnitude amplification of light from Ag 2 S QDs in NIR-II.
