Approximately 30% of global carbon dioxide (CO2) emissions are removed by terrestrial vegetation through photosynthesis.

Abstract: Optical properties of zinc sulfide (ZnS) nanotube (NT) are tuned by changing its chirality and adsorbing phosphorous. It is found that Armchair (4, 4) ZnS NT results in largest absorption ...

For precise characterizations of single-walled carbon nanotubes (SWCNTs) by optical absorption spectroscopy, the background extinction that originated from precipitable impurities and SWCNT bundles ...

Optical band gap and absorption coefficient are the two important parameters of a solar cell material. In the present study, optical characterization was done for the determination of the nature of ...

The materials enable light absorption in the absorption edge region, and the quantity is measured from the optical absorption coefficient (α). The physical meaning of α is the fractional attenuation ...

We report on the nonlinear optical properties measurements and quantum-chemical calculations of a well-known photochromic system consisting of spiropyran and the merocyanine photoproduct. The study of ...

Graphene, which is a zero-bandgap material, naturally overcomes this problem as its linear band structure ensures that its optical absorption coefficient is almost constant from visible to ...

Abstract: We present a novel method to extract the optical absorption coefficient of a semiconductor electroabsorption modulator (EAM) with antireflection coated facets. Only the transmission and ...
