Abstract:	摘要： We numerically investigated the surface plasmon resonance effects on photocatalytic activities using silver nanobeads photodeposited onto a titanium dioxide (TiO2) layer by three-dimensional finite element method. Results show that the proposed case C structure exhibits significantly high photocatalytic activity in a wide range of incident angle of light and broad wavelength range in near-UV, visible and near-infrared. The enhanced electric field region, intensity and peak resonance wavelength could be increased by enhancing the inner medium dielectric constant (ε) in silver nanobeads with ε in the range 1.7689–11.56 and the incident angle of light θ in the range 30°–75°. 出版者： Elsevier B.V 出版日期： 2014-11-15 出處： Optics communications, 2014-11, Vol.331, p.223-228 資源來源： ScienceDirect 版權： 2014 Elsevier B.V. 識別號： ISSN: 0030-4018 識別號： EISSN: 1873-0310 識別號： DOI: 10.1016/j.optcom.2014.06.018
