Fig. 2: Fabrication and characterization of photostable PNC films.

aSchematic representation of photostable PNC film fabrication that incorporates sequential spin-coating, thermal annealing, and preillumination processes. SEM images of the PNC films (b) before and (c) after the thermal annealing treatments and the corresponding (d) XRD patterns. e PL emission spectra and (f) PL stability for PNC films with different treatment procedures.
