Optical Constants and Optical Anisotropy of Ultrathin Gold Films

Advanced Photonics Research, 2023
Continuous and homogeneous thin gold films are fabricated on Si–SiO2 substrates using an additional seed layer based on Cu oxide or oxidized Cu. The optical properties of these gold films with thicknesses from 3 to 50 nm are studied with the help of ...

Variations in Infrared Complex Refractive Index Spectra of Surface Soils from Global Dust Entrainment Regions

Atmosphere, 2023
We explored spectral diversity in infrared (IR, 4–25 μm) imaginary (k) and real (n) indices of refraction (optical constants) for 26 surface soils that originated from global dust entrainment regions.
