Abstract
Measured fluorescence from single-particle clusters of dye-doped polystyrene microspheres, dried nonspherical particles of tryptophan, and single polystyrene microspheres is enhanced in the backward direction (180° from the incident laser). This enhancement (a factor of 2–3 compared to 90°), which can be interpreted as a consequence of the reciprocity principle, increases with the particle refractive index.
