| 中文摘要 | We propose a 3D aluminum funnel-antenna (FA) to enhance near-ultraviolet (UV) band absorption of a rutile TiO2 nanoparticle. The 3D finite-difference time-domain simulations show that rutile TiO2 nanoparticle placed within the antenna can significantly red shift its maximum absorption to the near-UV band around the mercury lamp 365 nm line, with a giant absorption cross section enhancement factor of more than two orders of magnitude. The field analysis indicates a significant 3D light harvesting effect, where the incident light energy impinging upon the wide-area antenna is efficiently collected, flows into the embedded TiO2 nanoparticle, and results in giant enhancement of local near-UV field intensity and effective absorption cross section. The design of the 3D aluminum FA opens up a promising way to boost the photocatalytic activity of TiO2 by using mercury lamp light. |
