Fluorescence spectra were measured of N-hexyl-naphthalimides absorbed on alumina particles, of which sizes were varied from 22 nm to 45 um, and the amount of the imides loading on the alumina particles were controlled so that logarithm of the coverage of the surface was the reach from -5 to +2. Naphtalimides which behaved as monomer or oligomer according to its amount were stabilized with alumina surface, and emission was red shifted than the fluorescence of the solution or neat crystals.
