Dexter energy transfer pathways [PDF]

Proceedings of the National Academy of Sciences, 2016
Significance Controlling the dynamics of excitons—including their transport, fission, fusion, and free carrier generation—presents a central challenge in energy science, optoelectronics, and photobiology. We develop a coupling-pathway theory for triplet energy transfer, a process controlled by the structure of the medium between donor and ...

Energy imparted, energy transferred and net energy transferred [PDF]

Physics in Medicine and Biology, 1983
The ICRU-defined non-stochastic quantity absorbed dose is related to the stochastic quantity energy imparted. In this paper the corresponding stochastic quantities energy transferred and net energy transferred are defined as precursors for kerma and collision kerma, respectively. This forms a rational fundamental framework for radiation dosimetry which
