Fig 5 The regulation of nanoparticles assembly by confining evaporation (a) Schematic diagram of the confined evaporation for generating stripe patterns of CdSe QDs on a silicon wafer. (b) The velocity profile of the translation stage for manipulating the stick-and-slip motion of the contact line. Schematic illustration of QD deposition at intermittent stopping times (ⅰ) and slipping of the contact line upon stage translation (ⅱ). (c) A fluorescent microscopy image of grid patterns. Scale bar, 200 μm. (d) Schematic diagram depicting the flexible-blade flow-coating process. Inset: illustration of a NP ribbon. (e) AFM image of OA-QD ribbons showing well-ordered structures. Inset: SEM image of the edge of a NP ribbon showing approximately monolayer particle packing (scale bar: 50 nm). (a–c) Reprinted with permission from Ref. 164. Copyright 2010 John Wiley and Sons.
