Fig. 3: Overview of the nature-inspired weathering processes in the single-crystal HOPE system.
From: Chemical weathering of molecular single crystals to monoliths of quantum dots
a Schematic representation of weathering processes leading to the formation of ZnO QDs. b The evolution of the time-resolved PXRD pattern during the HOPE SC transformation. c The HRTEM images of the final ZnO QD with the average size of 4.6 ± 0.6 nm. d The evolution of calculated QD diameter versus reaction time from in situ UV-Vis. e UV-Vis and PL spectra of ZnO QDs obtained by air exposure of HOPE SCs for 96 h. f Optical microscopy images of the HOPE SC upon exposure to air. g Single crystals of the HOPE after transformation photoexcited with 365 nm wavelength. h Optical microscopy images of the HOPE SC after weathering processes visualised with aligned polarizers. Needle-like crystals of BA-H at the HOPE surface are indicated by arrows. Source data are provided as a Source Data file.
