Development of Nanoparticles With Tunable UV Absorption Characteristics NANUVA
Abstract
This feasibility study will explore the possibility of using nanoparticles to precisely control absorption in the ultraviolet spectral region. While previous investigations have revealed a shift of optical resonances across the visible and infrared optical regions, to date, this effect has not been systematically demonstrated for the ultraviolet region.
In Phase 1 of this project, a systematic series of computer simulations and experiments conducted in parallel will be performed, where judicious material selection combined with varying the nanoparticles size will be used to derive conditions favorable to shifting the absorption edge within the ultraviolet region in a controlled manner.
In Phase 2, experiments will demonstrate the shifting of the absorption edge, established in Phase 1, by fabricating a device based on a nanoparticle assembly and measuring the photocurrent generated by this device in laboratory tests. Simulations will primarily be conducted in parallel by evaluating the core and shell materials and their thicknesses.
An industrial partner is keenly interested in incorporating a sensor based on the above-mentioned principles and would immediately implement such a sensor, if available, in an industrial system. This project, thus, extends the present frontier of nanoparticle applications and also fosters the development of nanotechnology.
