a Photochromism of Th-SINAP-100 upon UV-, β-ray, and γ-ray irradiation. The black scale bars in photographs represent 200 μm in length. b Evolution of the solid-state UV-Vis absorption spectra of Th-SINAP-100 crystal after exposure to 0–0.04 mJ UV irradiation doses (λex = 365 nm, 2 mW) at 25 °C. Inset: solid-state UV-Vis absorption spectra of Th-SINAP-100 crystal after exposure to 0.04–4.21 mJ UV irradiation dose. The UV-Vis spectra were collected on a crystal of Th-SINAP-100 from 250 to 800 nm based on the average intensities of 50 scans with a scan time of 2 ms. c Snapshots of bulk Th-SINAP-100 crystals upon 365 nm UV irradiation. d Evolution of the solid-state photoluminescence (PL) spectra of Th-SINAP-100 crystal after exposure to 0–4.21 mJ UV irradiation doses (λex = 365 nm, 2 mW) at 25 °C. Inset: PL spectra of Th-SINAP-100 after exposure to 0–0.04 mJ UV irradiation doses. The PL spectra were collected on a crystal of Th-SINAP-100 from 400 to 800 nm based on the average intensities of 5 scans with a scan time of 500 ms.
