CHEM 334 Quantitative Analysis Laboratory
Different visible absorption spectra and the concentration of copper and nickel can be determined spectrophotometrically. Zinc has no visible absorption spectrum but in the case of this ternary alloy, the concentration of zinc can be found by difference from the copper and nickel content. ... Read Here

Enhancement Of Optical absorption In Thin-film Organic Solar ...
The absorption spectrum in the silver region exhibits a sharp peak at =430 nm. Examining the field pattern at this peak Fig. 1 d , we note that it is associated with a surface plas-mon mode that is concentrated in the silver-glass interface SG-SP mode . Thus, the asymmetry in the structure, in the ... View Full Source
Nanofluid-Based Direct Absorption Solar Collector
Absorption spectrum is typically broadened14 while maintaining a distinct absorption peak leading to a further enhancement in the absorption efficiency through the solar spectrum. This broadening allows the nanofluid to absorb a larger portion of the spectrum, but maintaining a peak can allow ... Doc Retrieval

Optical Coating - Wikipedia
An optical coating is one or more thin layers of material deposited on an optical component such as a lens or mirror, which alters the way in which the optic reflects and transmits light. One type of optical coating is an antireflection coating , which reduces unwanted reflections from surfaces, and is commonly used on spectacle and ... Read Article
