From: Carbonized polymer dots enhanced stability and flexibility of quasi-2D perovskite photodetector
a The absorbance and (b) photoluminescence spectrum of CPDs-120 °C, pristine FMPI, and FMPI/CPDs-120 °C. c XRD and (d) XPS pattern of pristine FMPI and FMPI/CPDs thin films. e Built brief structure of CPDs with carboxylic acids, amides, and anhydrides groups, respectively. f The optimized structure and (g) differential charge analyses of CPDs with carboxylic acid group coordinate with unbonded Pb atoms
