TLDR
In this article, the authors show that neither the theory of energy transfer by exciton diffusion nor long range resonance energy transfer can adequately explain the experimental observations, and they also show that the predictions of the theory do not agree with the observed fluorescence rise times reported previously by other workers.Abstract:
This paper summarizes the results we have obtained in studying energy transfer in doped organic crystals as a function of temperature, dopent concentration, sample size, method of crystal growth and method of excitation. Neither the theory of energy transfer by exciton diffusion nor the theory of long range resonance energy transfer can adequately explain the experimental observations. We also show that the predictions of exciton diffusion do not agree with the observed fluorescence rise times reported previously by other workers. Unsuccessful attempts to fit the data with a theory of exciton diffusion in two dimensions are also reported.read more

Singlet exciton energy transfer in organic solids
Richard C. Powell,Z. G. Soos +1 more
TL;DR: A comprehensive review of the experimental data which have been obtained on singlet exciton energy transfer in organic crystals is presented in this article, where the usefulness of different types of experimental techniques in elucidating the characteristics of both exciton migration and trapping is discussed.

Time-resolved Förster energy transfer in polymer blends
TL;DR: In this article, the authors showed that insufficient spectral overlap between the emission of the host and absorption of the guest is the cause for the absence of energy transfer in a blend with poly(2,5-bis(cholestanoxy)-1,4-phenylenevinylene) (BCHA-PPV) as the guest polymer.

Light harvesting vesicular donor–acceptor scaffold limits the rate of charge recombination in the presence of an electron donor
TL;DR: In this article, the synthesis and excited state properties of a single component light harvesting donor-acceptor dyad (R/S)-NP(OH)2 containing an α,β-dihydroxypropyl side-chain that can undergo molecule-bilayer-vesicle-gel-crystal transition were reported.

The mathematics of diffusion
TL;DR: Though it incorporates much new material, this new edition preserves the general character of the book in providing a collection of solutions of the equations of diffusion and describing how these solutions may be obtained.

A Theory of Sensitized Luminescence in Solids
TL;DR: In this article, the resonance theory of Forster, which involves only allowed transitions, is extended to include transfer by means of forbidden transitions which, it is concluded, are responsible for the transfer in all inorganic systems yet investigated.
