Fig. 3

a SEM images of the morphology of LCPC-D and b thickness of the polymer shell (The scale bars are 10 μm and 1 μm). c Cross-sectional image of the LCPC film (The scale bar is 10 μm). d Orientation of helical superstructures in microcapsules. Contour maps of e LCPC-S, f LCPC-D, and g LCPC-T, showing the changes in fluorescent intensity with UV irradiation time (λex = 365 nm, 1.0 mW/cm2). The color gradient represents the fluorescence intensity, with red for high value and blue for none emission. h Fluorescent images of LCPCs with increasing of UV irradiation time (1.0 mW/cm2). i CIE chromaticity diagram of LCPC films in PSS365. j CPL spectra of LCPCs in PSS365 (λex = 365 nm) (blue line for LCPC-S, green line for LCPC-D in PSS365, and red line for LCPC-T in PSS365).
