Near-infrared Photoluminescent Ag2S Quantum Dots from a Single Source Precursor
Monodisperse Ag2S quantum dots (QDs) were synthesized via pyrolysis of Ag(DDTC) in oleic acid, octadecylamine, and I-octadecene. The uniform alkyl-capped Ag2S QDs with a size of 10.2 nm emit near-IR emission at 1058 nm under 785 nm excitation.
