Fig. 2: The growth mechanism and characterization of the blue-olive-blue triblock heterostructure nanowires.
From: Lattice-mismatch-free growth of organic heterostructure nanowires from cocrystals to alloys
a Schematic representation of the four-stage growth process of blue-olive-blue triblock heterostructures. FM images recorded during stage 1 (b), 2 (c), and 3 (d), 4 (e), respectively. The scale bar is 50 μm. The growing tips are magnified in the white squares. f, g Bright-field and FM image of individual blue-olive-blue triblock nanowire. The scale bar is 20 μm. h PL spectra collected from different sections marked in (g). The inset corresponds to the FM images of different positions excited by laser beam λ = 375 nm. The scale bar is 10 μm. i TEM images of triblock nanowires. The scale bar is 10 μm. Insets: corresponding SAED patterns of the central part (lower left) and the tip (upper right) of a single triblock nanowire.
