Fluorescence quantum yield (ϕf) of some highly fluorescent phenanthrene and phenanthrene-like derivatives has been measured using diphenyl anthracene as reference in ethanol.

The experimental critical transfer distances, Ro, between some of these compounds and rhodamine 6G, 2,5-Distyryl pyrazine (DSP) and 1,4-Bis (β-Pyraidyl-2-Vinyl) Benzene (P2VB) laser dyes have been studied using steady state emission in isopropanol giving values in the range from 29.6 to 57.6 Å. The underlying mechanism of energy transfer is that of Förster type.
