By manipulating the molecular distance between the electron - donating molecule (donor) and the electron - accepting molecule (acceptor) that carry the exciplex's hole and electron, respectively, the researchers could modify the properties of these weakly bound excitons.

«By increasing the thickness of an extremely thin layer of organic molecules inserted as a spacer between the donor and acceptor, we could reduce the attraction between the hole and electron in the exciplex and thereby greatly influence the exciplex's energy, lifetime, and emission color and efficiency.»

This device was first reported in the paper titled «Long - range coupling of electron - hole pairs in spatially separated organic donor - acceptor layers» written by H.

Abstract: Although it is known that molecular interactions govern morphology formation and purity of mixed domains of conjugated polymer donors and small - molecule acceptors, and thus largely control the achievable performance of organic solar cells, quantifying interaction - function relations has remained elusive.

The simplest and the most popular one is the sensitised emission method, where the donor is excited by a specific wavelength of light and the signal is collected by using emission filters chosen for the donor fluorescence and the acceptor fluorescence.

In their JCB 2003 paper, Sekar and Periasamy defined FRET as «a distance - dependent physical process by which energy is transferred non-radiatively from an excited molecular fluorophore (the donor) to another fluorophore (the acceptor) by means of intermolecular long - range dipole - dipole coupling.»

Here the bioluminescent donor is unaffected by activation of other fluorescent probes but can still transfer energy to the fluorescent protein acceptor.
