From: Synthesis of Au@polymer nanohybrids with transited core-shell morphology from concentric to eccentric Emoji-N or Janus nanoparticles

Figure 4

(a) Schematic depiction of eccentric or Janus core-shell nanohybrids consisting of pSt shell coverage anisotropically grown on AuNP; (b) S-TEM images of distinct morphologies of Au@pSt nanohybrids obtained with ethanol concentration increasing: (b-i) G8, (b-ii) G9, (b-iii) G10 at different magnification, and (b-iv) G11. Right-hand of (b-ii) illustrates SEM image of G9; (c) Size diameter by intensity distribution and (d) Extinction spectra of AuNP and the corresponding G8-G11 nanohybrids shown in b (i-iv). Inset: color variation of the Au@pSt nanohybrid solutions with shell-morphology evolution from concentric core-shell to eccentric and Janus-NPs.
