Metal plasmon enhanced luminescence of rhodamine B

Abstract

The role played by surface plasmon in metal NPs-dye interaction is discussed. Importance of the optical spacer is addressed based on time resolved photoluminescence experiments. The potential application of metal NPs surface plasmon to organic light emitting diodes is highlighted.

“…However, with further decrease of the Alq 3 thickness to 20 nm, the enhancement factor decreases somewhat which suggests that emission centers start shifting away from their optimal enhancement position. 26,27 It is worth mentioning that all devices prpared with 1 nm Ag NPs layer exhibit improved current density, regardless of the Alq 3 deposition thickness, which further confirms our lightning rod impelled electron injection interpretation.…”
