| Abstract: | In order to study the growth of nanocrystals in solutions, an in-situ real-time optical absorption spectral system is designed and realized. In-situ spectral detection is performed to trace the growth of PbS nano-wires and nano-dots in aqueous solutions. It is found that the addtion of SDS plays an important role in the growth of PbS nanocrystals in preferential directions. |
