متن کاملNonlinear Responses and Optical Limiting Behavior of Ag Nanoparticle Suspension
In this study, the nonlinear optical properties and optical limiting performance of the silver nanoparticles (AgNPs) in distilled water are investigated. The nonlinear absorption coefficient of the colloid is measured by the Z-scan technique. The optical limiting behavior of the AgNP suspension is investigated under exposure to nanosecond laser pulses at 532 nm. The results show that nonlinear ...
متن کاملAnomalous absorption of light by a nanoparticle and bistability in the presence of resonant fluorescent atom
Absorption of light by a nanoparticle in the presence of resonant atom and fluorescence of the latter are theoretically investigated. It is shown, that absorption of light by a nanoparticle can be increased by several orders because of presence of atom. It is established, that optical bistability in such system is possible. PACS numbers: 42.50.Ct, 12.20.-m, 42.60.Da, 42.50.Lc, 42.50.Pq, 42.50.Nn
متن کاملEFFECT OF MULTI-STEP ANODIZING METHODS ON THE OPTICAL ABSORPTION OF BLACK COATINGS ON 2024 ALUMINUM ALLOY
Development of materials with the ideal black body absorption spectrum are of great interest. Such materials could improve the efficiency of solar cells, and passive cooling and heat transfer systems as well as the protective and decorative coatings. Fabricating black anodizing coatings is promising for this purpose because they exhibit low light reflection from the surface. Such coatings can ...
