The conversion and manipulation of light via lanthanide-based upconversion (UC) and downshifting (DS) show promise in numerous applications. We demonstrate the lanthanide-doped nanotemplates to improve conversion of ultraviolet and near-infrared to visible light through resonant-mode excitation. The templates are fabricated using nanoimprint technique wherein ordered arrays of nanoscale features are readily made over large areas. The practical applicability of this platform in photovoltaic devices is evaluated, showing distinctively enhanced efficiency. The material-agnostic nanopatterning methodology is further extended to nanopatterned thin films synthesized by a sol-gel-based solution to achieve simultaneous photonic and electrical enhancements in thin film photovoltaic devices. |
