Metal surface plasmons(SPs)are in the focus by a wide spectrum of scientists,ranging from physicists,chemists and materials scientists to biologists [1].By altering the shape,size,structure and dielectric environment of the metal nanomaterial,the properties of SPs,in particular their interaction with light,can be tailored,which offers the potential for developing new types of photodetection device [2].
