Plasmon-enhanced upconversion particles for dye-sensitized solar cells |
| 초록 |
Upconversion particles (UCPs) have luminescent property that converts a near-infrared extinction into a visible emission. Among these UCPs, the β-NaYF4 host lattice doped with lanthanide Yb3+ and Er3+ has been shown to be the most efficient UCP. However, upconversion process generally suffers from low quantum efficiency. Metal nanoparticles such as Ag or Au are known to enhance extinction and emission process by local field amplication and enhancing radiative decay rates. Herein we incorporated the Au decorated β-NaYF4 into the photoanode of dye-sensitized solar cell. The LSPR effects from Au NPs could enhance the upconversion efficiency. Moreover the light utilization in the photoanode was increased by light scattering and plasmon-enhanced light absorption. |
