• /nanopore; nano/microstructures; SERS substrate; Introduction Surface-enhanced Raman spectroscopy (SERS) can be used to detect biomolecules [1][2][3], explosives [4][5][6], and pesticide residues [7][8][9]. Plasmonic metal nanostructures are often used as SERS substrates to increase the molecule-specific

• parameters of plasmonic metal nanostructures such as particle size, work function, surface facet and plasmonic band is a challenging task that demands numerical simulation. It is known that the photocatalysis performance is affected by the noble metal particle size and thus finite difference time domain

Plasmonic-metal nanostructures are also promising for increasing the conversion efficiency of solar energy directly into chemical energy (see review in [7]), such as in plasmon-enhanced water splitting. These systems depend on the close interaction between metallic nanoparticles and

Also, since nonradiative recombination is an alternative to the radiative emission process in the nanophosphors, we may expect to learn more about the transfer of charge between metal and nonmetal from
