Fig. 4: PL intensity and recombination lifetime mapping for ferroelastic domains.

a is polarized optical microscope image with resolved domain patterns, the golden square corresponds to the non-polarized optical microscope image in (b); the blue square in (b) is the mapping area; c and d are the corresponding PL intensity and PL recombination lifetime mapping results, respectively.
