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