MODIFICATION OF SPONTANEOUS EMISSION FROM PERIODIC ARRAY OF SPHERICAL POLYSTYRENE PARTICLES CONTAINING FLUORESCENT MOLECULES

摘要

Emissive behavior of dye molecules embedded in the systems with the size of visible wavelength were studied. The structures consisted of close-packed arrays of spherical dielectric particles with diameter of submicrometer were fabricated. Photoluminescence from self-assembled arrays of dye-doped polystyrene microspheres were examined. In this systems, partial suppression of spontaneous emission by ordered structures were observed. Electrically-pumped emission from organic light emitting diodes with highly ordered arrays of silica microspheres were attempted.
