“…This is not of course a real shift but a result of the fact that the SPPs influence is not in the thin film models, and the position of the SPP changes when the neighbouring dielectric changes, because the evanescent fields are altered. Anomalous absorption then occurs [10,11]. For metal layers with nanostructure we find significant apparent shift [4], but when we model the stack of Al 2 O 3 on top of a mesoporous layer we can fit the stack data very well without modifying the metal layer's optical constants.…”

“…However detailed analysis and recent experiments [10,11] show that additional absorption will occur at the interface due to the excitation of SPPs, and thus that standard thin film models cannot fully describe the optical properties of such films. One approach to include this effect in standard models is to introduce an additional very thin layer at the interface to obtain a fit [11]. While such a "non-physical" layer may yield a fit to optical data by "allowing" more light to enter the layer and be absorbed, there is no a priori way of establishing its properties without an understanding of the link between surface nanostructure and SPP characteristics.…”

The far-field plasmonic behaviour of nanoporous gold films with void densities, f, ranging from 60% to 90% has been investigated and modelled. These layers have good dc conductivity and quite different nanostructure to traditional porous layers in which the metal percolates. Our gold films with f above 70% have high thermal emittance for a conductor at their thicknesses, and their flat spectral response at visible and near infrared wavelengths is not metal-like. We derive effective optical constants which become plasmonic at wavelengths between 1.8 m and 4 m for f from 72% to 87%. This onset is at much longer wavelengths than that in bulk gold. For f below 70% the onset of plasmonic behaviour is much closer to the dense material. A simple test is implemented to test for surface plasmon polaritons (SPP) under illumination. The more porous films show no evidence of SPP, while the less porous films display weak evidence. Thus by tailoring f in these nanostructures we can tailor the onset of effective plasmonic response across a wide range and emittance from around 0.9 down to low values. An effective uniform metal response is thus found in the presence of surface nanostructure without the interface absorption found in dense gold layers with structured surfaces.

Am beispiel der Abscheidung von low-e Schichten auf verschiedene Kunststoff oberflächen konnte der einfluss der oberflächenrauheit auf die funktionellen eigen schaften diskutiert werden. bei der Verwendung rauer oberflächen wird eine verstärkte Absorption im sichtbaren Spektralbereich beobachtet, welche auf oberflächenplasmonen verluste zurückzuführen ist. für die Verbesserung der Trans mis sion (T vis ) muss folglich ein Substrat mit geringer rauheit ver wendet werden.

Formation of double‐surface‐silvered polyimide films via a direct ion‐exchange self‐metallization technique: The case of BPADA/ODA and [Ag(NH₃)₂]⁺

Double‐surface‐silvered polyimide (PI) films have been successfully fabricated via a direct ion‐exchange self‐metallization method using silver ammonia complex cation ([Ag(NH3)2]+) as silver resource and bis[4‐(3,4‐dicarboxyphenoxy)phenyl]propane dianhydride/4,4′‐oxydianiline (BPADA/ODA)‐based poly(amic acid) (PAA) as the PI precursor. The alkaline characteristic of the silver precursor dramatically improves the efficiency of the ion exchange and film metallization process. By using an aqueous [Ag(NH3)2]+ solution with a concentration of only 0.01M and an ion‐exchange time of only 5 min, metallized films with desirable performance could be easily obtained by simply heating the silver(I)‐doped PAA films to 300°C. The strong hydrolysis effect of the basic [Ag(NH3)2]+ cations on the flexible and acidic BPADA/ODA PAA chains was observed during the ion exchange process by the quantitative evaluation of the mass loss of PAA matrix. Nevertheless, under the present experimental conditions, the final metallized film essentially retained the basic structural, thermal, and mechanical properties of the pristine PI, which make it a truly applicable material. © 2012 Wiley Periodicals, Inc.
