Abstract

3D-ordered latex films made of fluorescent microspheres were fabricated by sonication-assisted casting. Angledependent changes of photoluminescent (PL) emission were observed for the as-prepared fluorescent latex films with diameter of 200 nm. The PL emission at 483 and 512 nm was enhanced when they were near the edge of the stop band, and the suppression of PL emission was observed at 483 and 512 nm when they were located in the stop band. Resonance enhancement of PL emission was observed at 512 nm for the latex film with latex diameter of 1011 nm, in which the fluorescent sphere acted as both active emitting source and resonance microcavity.
