Three types of thin solid films with the nanoscale inner structures were synthesized by sputtering-deposition and anodizing of Al layer, Al-1.5at.% Si alloy layer, and Al/Ta bilayer on Si wafers. All the anodic films comprised 1μm thick nanoporous alumina layer as the key component. The essential differences were due to the silicon impurities (AlSi alloy) and the array of nanosized tantalum oxide...
Optical properties of ultraviolet (UV)-light soaked states in poly(9,9-dioctylfluorene) (F8) have been studied. F8 thin films, synthesized by Suzuki and Yamamoto coupling reactions, were irradiated by a He–Cd laser (λ=325 nm) and the UV-light-soaked states were characterized by photoluminescence (PL), optical absorption, Fourier transform infrared absorption and electron spectroscopy for chemical...
