The amplification of light in NIR-II from Ag2S QDs via metal enhanced fluorescence (MEF) is reported for the first time. Significant enhancement over 100 times deposited on Au-nanostructured arrays, paves way novel sensing and imaging applications based QDs, with improved detection sensitivity contrast enhancement.
