Values of maximum excitation pressure over PSII (Qm), the effective quantum yield at midday relative to maximum quantum yield (see Methods), reflected the differences between cold and heat-treated corals.
The yield is at its maximum from 5 to 25 years later.
Its quantum yield and emission maximum are highly sensitive to the polarity of its local environment [ 26, 27].
At the distance where the suppression zone yields to the eradication zone, optimal detection effort plateaus at its maximum level.
Φ = (A 1 − A 0 ) N A 10 3 × ε × Ι × (1 − 10 (A 1 + A 0 ) / 2 ) (t 1 − t 0 ) (1)where Φ is the photodecomposition quantum yield, A1 is absorbance maximum at t1, A0 is absorbance maximum at t0, NA is Avogadro's number, ε is molar absorbance, t1-t0 is exposure time (s), and I is the intensity in photon · sec−1 · cm−2.
The resulting pre-PET/NIRF probe 1 shows long wavelength NIR fluorescence and adequate quantum yield [excitation maximum = 755 nm, emission maximum = 772 nm, and φf = 0.027].
Moreover, they offer high photoluminescence quantum yields at room temperature.

(a) Effective quantum yield (ΔF/Fm'), (b) maximum quantum yield (Fv/Fm), and (c) maximum excitation pressure over photosystem II (Qm) over time during the experiment (mean ± s.e.m.; N = 10−19 for 0 9 d, N = 5−8 for 12 20 d).
Increasing the heating time led to increased PL quantum yield, and maxima occurred at 120 min. Such PL quantum yield increase could be ascribed to the improvement of the crystallization and annealing effect of defects.
Two-way ANOVAs and t-tests of effective quantum yield and maximum quantum yield reveal significant effects of treatment (P<0.0001), time (P<0.0001), and treatment x time (P<0.0001) (Supplementary Tables S1 and S2 online).
