Abstract
We present phosphorescence enhancement of 2,5-dihexyloxy-4-bromobenzaldehyde (Br6A), a metal-free organic phosphor, by means of Ag nanoparticles (NPs) through surface plasmon excitation. The emission enhancement and lifetime reduction was observed in the fluorescence and phosphorescence suggesting that the phosphorescence enhancement can be achieved in the same manner as in fluorescence, through the increase of photoabsorption and the enhanced emission rate by the field enhancement around the metal nanostructures. Our results help to improve the understanding of the phosphorescence enhancement mechanism of a new class of purely organic phosphors. © 2017 Elsevier B.V
