Enhancement of Light Trapping and Optical Absorption in Complex ZnO Nanostructures
Abstract
The major goals of the proposed project is to study and demonstrate the enhanced light trapping and optical absorption in complex ZnO nanostructures with novel geometries and morphologies based on new solution-phase bottom-up nanosynthesis methods, in order to gain fundamental understanding of light trapping and light-matter interactions in complex semiconductor nanostructures and plasmonics enhanced light trapping in metallic particles, and advance Armys capabilities in research areas of highly complex multifunctional materials with unprecedented properties and enhanced light-matter interactions. The specific objectives of this project include: (1) Design, fabricate, and characterize complex ZnO nanostructures for the enhancement of light trapping and optical absorption. Complex ZnO nanostructures will be designed and synthesized with new solution-phase structure-orientated nanosynthesis methods. The optical properties of complex ZnO nanostructures for enhanced light trapping and optical absorption will be analyzed. Optical spectra measurements and photoelectrochemical measurements will be conducted to characterize the optical absorption properties of complex ZnO nanostructures. (2) Investigate plasmonics enhanced light trapping and optical absorption in complex metallic nanostructures. Metallic nanostructures will be studied for potential coupling with complex ZnO nanostructures. Numerical simulations will be performed to understand the plasmonics effects on the light scattering, light trapping and optical absorption in metallic nanostructures and ZnO nanostructures. The plasmonics enhanced optical absorption will be investigated with optical spectra measurements and photoelectrochemical measurements.
