单分散硫化银量子点(QDs)通过在油酸、十八胺和1 - 十八烯中热解Ag(DDTC)来合成。尺寸为10.2 nm且具有均匀烷基封端的硫化银量子点在785 nm激发下于1058 nm处发射近红外光。
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.
