Nanomaterials for light management in electro-optical devices

摘要: In the past decade, nanostructured materials and nanoparticles have emerged as necessary ingredients for electrooptical applications enhancement of device performance, in particular by making use light management aspects nanomaterials. The application areas that are being transformed profoundly include smart coating devices (e.g., electrochromic, photochromic, thermochromic devices), solar energy, sensing. Despite large volume work on devices, electrochromic fenestrations, optical transmission or reflection control, remain limited because slow response time nonuniformity case surfaces. Recent works field indicate coatings would be an integral part solution to above problem. One aspect can thus focused fabrication characterization their compatibility with other layers overall device. area photovoltaics, nanomaterials been used designing light-trapping schemes inorganic well organic cells. category cells has attracted much interest is plasmonic which metallic incorporated, helpingmore » enhancing energy conversion efficiency. Nanostructured eventually develop into a 'game changing' technology affordable highly efficient, providing sizeable alternative source our ever-increasing needs. Sensors based properties constituting nanostructures also form most interesting class bio- electrochemical sensing devices. possibility synthetizing structures specifically desired sizes shapes indeed opened whole new range applications. parallel experimental development theoretical modeling analysis accomplished progress, different methods simulating proposed. This special issue Journal Nanomaterials dedicated articles dealing purpose Silicon-rich oxide (SRO) dielectric material contains Si exhibits physical characteristics optoelectronic Aceves-Mijares et al. examine, detail electro-, cathode- photoluminescence SRO discuss origin emission this type materials. films, high medium silicon excess density, obtained low-pressure chemical vapor deposition annealed at 1,100 C studied. Results authors led conclude due oxidation state nanoagglomerates rather than nanocrystals, mechanism similar donor-acceptor decay semiconductors specific wide spectrum. Two papers devoted thin suitable controlling absorption including window coatings.
