Synthesis and Spectral Analysis of Head-to-Tail Shaped Ag2S/ZnS Near-Infrared Quantum Dots with Manganese Dopant.

Abstract

Silver sulfide (Ag2S) near-infrared quantum dots have been synthesized by one pot process and the water solubility of the quantum dots was enhanced by ligand exchange. With the addition of zinc source, zinc sulfide (ZnS) nanocrystals grew like a link with the Ag2S in head-to-tail structure. Furthermore, in the presence of manganese dopants, particles… (More)
