Figure 1From: Shape and phase control of CdS nanocrystals using cationic surfactant in noninjection synthesis TEM images of the CdS nanocrystals obtained with different amounts of CTAC added: (a) 0 mmol, (b) 0.25 mmol, (c) 0.5 mmol, and (d) 1 mmol. A shape transformation from spherical to multi-armed was observed with the increase of the amount of CTAC.Back to article page
