Nitrogen dots as reductant and stabilizer for the synthesis of AgNPs/N-dots nanocomposites for efficient surface-enhanced Raman scattering detection.


A simple method was developed for the preparation of silver nanoparticles (AgNPs) by using amino-functionalized nitrogen dots (N-dots) as reductant and stabilizer under mild conditions. N-dots were hydrothermal synthesized using 2-azidoimidazole as the precursor in aqueous ammonia. The as prepared N-dots were rich in nitrogen and oxygen-containing… (More)
