a The synthesis and assembly illustration of Pt-CDs to HS-Pt-CDs. AFM images and the height profile analysis (inset) of (b) Pt-CDs and (c) HS-Pt-CDs. d TEM and (e) representative AC-HAADF-STEM images of the HS-Pt-CDs. Black circles represent Pt atom. f EDX elements mapping images of HS-Pt-CDs. g Intensity profile of the atoms dash line in regions of (e) and IFFT pattern of HRTEM (inset). h The Moiré pattern of HRTEM. Purple dashed lines represent dislocations, blue dashed lines represent lattice fringes. Line-scanning intensity profile obtained from the area highlighted with (1) orange lines and (2) blue lines in (h). i Strain fields mapping of (e) HAADF imaging by geometric phase analysis (GPA) with horizontal normal strain components εxx. The color scale denotes the strain intensity changes from −1.0% (compressive) to 1.0% (tensile). The area of dashed lines indicates the areas around the dislocations
