Kinetics of Pb→Pg photoconversion and Pg→Pb thermal reversion for TePixJ(GAF) in crystallo. (A) Absorption spectra were collected at 23 °C for crushed TePixJ(GAF) crystals during continuous irradiation with blue-light fluence rates of 4 μmol⋅m⁻²⋅s⁻¹ (Left) or 0.4 μmol⋅m⁻²⋅s⁻¹ (Right). The initial spectra (t₀, black line) were collected for the dark-adapted Pb state. (A, Insets) Absorption changes at 540 nm during the photoconversion of the crystals. (B) Crystals of TePixJ(GAF) revert thermally from Pg back to the dark-adapted Pb state. The initial spectrum (green line) was collected for Pg immediately after photoconversion with saturating blue light. Absorption spectra were then collected at the indicated incubation times in darkness at 23 °C. The spectral traces are offset for clarity. Absorption maxima are indicated.
