Room-Temperature Wurtzite ZnS Nanocrystal Growth on Zn Finger-like Peptide Nanotubes by Controlling Their Unfolding Peptide Structures

摘要

A class of wide-gap II-VI semiconductor nanomaterials has shown interesting optical,electrical,and optoelectric properties via quantum confinement.ZnS nanocrystals have attracted considerable attention due to its applications in flat-panel displays,electroluminescent devices,infrared windows,sensors,and lasers.For those applications,phase controls of ZnS nanocrystals were critical to tune their physical properties to the appropriate ones.From the industrial point of view,the wurtzite ZnS nanocrystal fabrication at room temperature is extremely practical;however,the most stable ZnS structure in nanoscale is the zinc blende (cubic) structure,and scientists have just begun exploring the room-temperature synthesis of the wurtzite structure of ZnS nanocrystals.
