“…In this search, the sun appears as a clean source of energy with lifetime over 5000 million years releasing daily 4000 times the earth electric energy consumption. The use of solar energy can be addressed by different techniques including photovoltaic [104,105,106,107], photochemical [108,109,110] or photothermal [111,112,113] Increases of photovoltaic cells efficiency of the order of 10-15% have been achieved by incorporating Au and Ag NPs on the cell surface [119,120,121,122,123]. The efficiency in this kind of devices has a complex dependence on the NPs size, shape and spatial distribution, since interacting effects play a different role on the light scattering and absorption processes [116].…”

The excitation of surface plasmons in metallic nanoparticles induces optical properties hardly achievable in other optical materials, yielding a wide range of applications in many fields. This review presents an overview of surface plasmons in metallic nanoparticles. The concept of surface plasmons in nanoparticles is qualitatively described using a comparison with simple linear oscillators. The mathematical models to carry on calculations on surface plasmons are presented as well as the most common approximations. The different parameters governing the features of surface plasmons and their effect on the optical properties of the materials are reviewed. Finally, applications of surface plasmons in different fields as biomedicine, energy, environment protection and information technology are revised.

“…From eqs 5 and 6, the following relation is obtained (7) zo/z = 1 + k q / ( k f + kd) = The distance between Cz and X-Py depends linearly on the distance of X-Py to X-Py (2R), which is calculated from the two-dimensional density (n, (molecules/nm2)) of X-Py in the monolayer matrix (R = (%/x)-l12 (nm)). The plots of In (lo/l -1) vs R for the quenching of three kinds of DDA/Cz copolymer monolayers by the COCH3-Py quencher are shown in Figure 8.…”

Electron-transfer quenching of the excited carbazole chromophore in poly(N-dodecylacrylamid~c~~-~yl~rbazole)s (DDA/Cz) polymer monolayers by three different N-stearyl para-substituted pyridinium derivatives (X-Py) (p-COCH,, p-COOCH3, and pCONH2) has been investigated in LangmukBlodgett (LB) assembly systems by using a steady-state emission quenching method. Three different mixed monolayers of the pyridiniums with stearic acid (St) are in direct contact with the DDA/Cz monolayers having various Cz contents to investigate the influence of the redox potentials of the quenchers and the effect of energy migration between the Cz chromophores on the electron-transfer quenching in the LB films. The emission of the excited carbazole was quenched effectively by a small amount of the pyridinium quencher with a help of energy migration between the Cz chromophores. The quenching efficiency was varied by the mole fraction of carbazole contents, which is related to the density of excimer site in the monolayer and by the redox potentials of the pyridiniums. The plots of In (Zo/Z -1) (I in the presence and Z , in the absence of the quencher) vs distance (R) between the quenchers gave a linear relationship for all the quenchen. The mechanism of electron-transfer quenching in the LB film assembly is discussed on the basis of electron tunneling and energy migration.
