Here we report on the experimental details of a study on the influence of the photonic environment on the emission of a FRET system. We modified the local density of optical states (LDOS) by placing the FRET system at precisely defined distances to a metallic mirror. We measured the energy donor lifetime in the presence of the FRET acceptor and the lifetime of an identical sample lacking an acceptor fluorophore for different LDOS. From the lifetimes we determined the FRET rate as well as the FRET efficiency for each sampled LDOS.
