Figure Lengend Snippet: SEM images of the perovskite films ( A ) without and ( B ) with 15C5, ( C ) with 15C5 after EHE, and with ( D ) 12C4, ( E ) 18C6, ( F ) DB21C7, and ( G ) DB24C8. HRTEM images (as well as the corresponding magnified views) and SAED patterns of the perovskite films ( H and I ) without and ( K and L ) with 15C5, respectively. ( J ) Schematic diagram of Turing structures, including original perovskites (matrix phase) as a local activator and SMHCs (induced phase) as a lateral inhibitor, as well as clear Turing interfaces.
Article Snippet: HRTEM images and SAED patterns were obtained by a FEI Tecnai F20. fs-TA spectroscopy and time-resolved PL (TRPL) decay kinetics were collected by using Light Conversion Harpia, which used 400-nm femtosecond-resolution laser excitation.
