Title (EN) PLASMON ENHANCED PHOTO PROCESSES
(FR) PHOTOTRAITEMENTS AMELIORES PAR L'EFFET DE RESONANCE DU PLASMON
Abstract:
(EN) Methods and apparatus provided with selected nanoparticles that exhibit the plasmon resonance effect to enhance photoprocesses. In a first embodiment, such nanoparticles are used in a method of forming an integrated circuit; and in additional embodiments, the nanoparticles are used to increase the catalytic effect of a metal catalyst to increase the rate at which molecules absorb light, to accelerate the reduction of carbon dioxide to formic acid, to accelerate the decomposition of pollutants, and to accelerate the reaction of two reactants to produce a fuel. Additional embodiments utilize the plasmon resonance effect to enhance the effect of solar energy on a solar responsive electrode of a photochemical battery, and to inhibit the passage of ultraviolet light through a sunscreen. Also, in accordance with the present invention, nanoparticles that exhibit the plasmon resonance effect are used to improve a test for a solution for a bio-agent, and to develop fingerprints on a surface.
(FR) Procédé et appareil utilisant des nanoparticules sélectionnées ayant un effet de résonance du plasmon pour améliorer les phototraitements. Dans un premier mode de réalisation, de telles manoparticules sont utilisées dans un procédé de formation d'un circuit intégré. Dans d'autres modes de réalisation, les nanoparticules sont utilisées pour augmenter l'effet catalytique d'un catalyseur métallique, pour augmenter la vitesse à laquelle les molecules absorbent de la lumière, pour accélérer la réduction de dioxyde de carbone sur l'acide formique, pour accélérer la décomposition d'agents polluants, et pour accélérer la réaction de deux réactants pour produire un combustible. Des modes supplémentaires de réalisation utilisent l'effet de résonance du plasmon pour augmenter l'effet de l'énergie solaire sur une électrode solaire d'une batterie photochimique, et pour inhiber le passage de lumière ultraviolette au travers d'un écran solaire. De même, selon la présente invention, des nanoparticules qui présentent l'effet de résonance du plasmon sont utilisées pour améliorer un test pour une solution d'un bioagent et pour développer des empreintes digitales sur une surface.
