Abstract
Plasmon-induced charge separation (PICS) by continuous electron injection from plasmonic compound nanoparticles to a semiconductor was achieved by using solid-state cells based on tin-doped indium oxide (ITO) nanoparticles with a short capping agent and a TiO2 film. The cells extended the PICS range to longer wavelengths and exhibited photoresponses to 1500-2200 nm near-infrared light.
摘要
通过使用具有短封端剂和 TiO2 薄膜的掺锡氧化铟（ITO）纳米颗粒的固态电池，实现了连续的电子从等离子体复合纳米粒子注入半导体的等离子体诱导电荷分离（PICS）。这些电池将 PICS 范围扩展到更长的波长，并对 1500-2200nm 近红外光表现出光响应。
