Abstract

The synthesis of narrowly dispersed colloidal lead sulfide (PbS) nanocrystals was discussed. The nanocrystals offered size-tunable near-infrared emission. Transmission electron microscopy (TEM) was used to characterize the nanocrystals. It was found that the particle growth occurred along the preferred crystal directions.
