a) Schematic illustration of phase patterning in a AuNC/PVDF film using direct laser writing technique. The 785 nm laser source in Raman microscope was used and the motion of the sample was driven by a software-controlled motorized stage installed in the microscope. b) Raman mapping collected over 250 × 250 μm2 area of AuNC/PVDF film, exhibiting a patterned β phase distribution. Bar: 50 μm. Representative Raman spectra of c) non-irradiated region (β phase-dominated) and d) laser-irradiated region (α phase-dominated) in AuNC/PVDF. e) Profile of phase content from the dash line indicated in b).
