图 7  (a), (b)分别为纳米枝晶正在生长为纳米花瓣时的TEM图和SEM图; (c)硫源释放S2– 速率过快导致CuS直接团聚而未能得到纳米花瓣; (d)自组装过程因能量不足导致大量纳米片散落

Fig. 7.  (a), (b) TEM and SEM images when nanocrystals are growing into nanocrystals, respectively; (c) the S2– release rate of sulfur source is too fast, which leads to direct aggregation of CuS and fails to obtain nanopetals; (d) a large number of nanosheets were scattered due to lack of energy during the self-assembly process.
