The couple and decouple processes at ZnO/Ag and Ag/ZnO grating interfaces were considered to confine the incident light to SPPs ͑near field͒ and then to excite the SPPs to radiate light ͑far field͒, which enhanced light transmission. A broad range of light transmission enhancement showed a blueshift with increasing Ag midlayer mass thickness. The physical reasons for light transmission enhancement were theoretically discussed using both the metal/dielectric grating interface model and the Drude-Lorentz free electron model.

Improvement of optical and electrical properties of indium tin oxide layer of GaN-based light-emitting diode by surface plasmon in silver nanoparticles

“…The coupled LSPs are then decoupled by the Ag nanoparticle grating and the enhanced light is re-emitted into free space. The coupling and decoupling processes also prevent the light from being reflected or scattered back to the incident side and thus enhance the light transmission [13][14][15]. For a metal/surrounding dielectric interface, the SP resonant wave vector can be written by solving the Maxwell equations as follows [16]:…”

From the Drude-Lorentz free electron model, the plasmon frequency (ω p ) can be expressed as the following equation: (1) hereHere, m is the effective mass of the electron, e is the electric charge, n is the carrier density of electrons, and ε 0 is the permittivity of free space [15,16].

High quality transparent TiO2/Ag/TiO2 composite electrode films deposited on flexible substrate at room temperature by sputtering

“…In the visible region, higher transmittance was observed which can also be explained on the coupling between the incident light and surface plasmon of the island like structures of Ag thin films. [24][25][26] However, in the longer wavelength (700-800 nm) region the transmittance decreased abruptly for larger Ag thickness (11-13 nm), a trend similar to the optical behavior of bulk metals. In the near IR region, the increase in electron carriers results in low transmission is due to plasmon absorption dependent reflection.…”
