In this article, Sensitized fluorescence of 3,9-dibromoperylene (DBP) was obtained from triplet energy transfer with ketones as donors.Abstract:
Sensitized fluorescence of 3,9-dibromoperylene (DBP) was obtained from triplet energy transfer with ketones as donors. The maximum efficiency of this process (TETSF) in acetonitrile measured with time-correlated single-photon counting was QTS = 0.33 ± 0.08. Because of the high quantum yield of fluorescence (QF = 0.75 ± 0.10) for analytical applications of TETSF DBP is superior to the acceptor molecules investigated earlier. Particular attention was paid to a detailed elucidation of the energy transfer processes involved in TETSF. The analysis of the excess energy dependence provided evidence for the participation of a higher excited triplet state (Tn) of DBP.read more

TL;DR: A better understanding of the mechanisms of tolerance to UV-B radiation and of the interaction betweenUV-B and other environmental factors is needed in order to adequately assess the probable consequences of a change in solar radiation.

UV-B damage and protection at the molecular level in plants.
TL;DR: This review summarizes the early effects and responses of low doses of UV-B at the molecular level and indicates that the integrity of the thylakoid membrane seems to be much more sensitive than the activities of the photosynthetic components bound within.

Effects of ultraviolet radiation on corals and other coral reef organisms
TL;DR: In this paper, the authors comprehensively review the effects of solar ultraviolet radiation (UVR) on corals and other reef macroorganisms, mindful that although much is known of proximal effects, little of this knowledge is directly useful in making long-term predictions regarding the health of coral reefs.

Influence of Energy Transfer by the Exchange Mechanism on Donor Luminescence
Mitio Inokuti,Fumio Hirayama +1 more
TL;DR: In this paper, the decay of donor luminescence in a rigid solution when modified by electronic energy transfer by the exchange mechanism is treated theoretically, and the rate constant for the elementary process of energy transfer is taken to be of the Dexter form, const exp(−2R/L), where R is the donor-acceptor distance and L is a positive constant.
