Plasmon-enhanced upconversion luminescence of NaYF4: Yb3+/ Er3+ co-doped nanocrystals is investigated using a 3D plasmonic antenna architecture: a disk-coupled dots-on-pillar antenna array (D2PA). By tuning and optimizing the resonance frequency of the D2PA structure for upconversion luminescence, a 310-fold luminescence enhancement and an 8-fold reduction of the luminescence decay time are observed.
