The three peaks arise from n = 1 exciton transitions involving holes from each one of the three valence bands. At 4.2°K the n = 2 exciton states become apparent in reflection, allowing estimates to be made of the exciton binding energy and reduced mass. In absorption the lowest energy ...
Zinc oxideis a multifunctional material because of its many interesting properties (piezo- and pyroelectric), a wide range of UV absorption, and high photostability, biocompatibility, and biodegradability. ZnO can also be obtained with a variety of particle structures, thin/thick films that determine...

The absorption peak is located at the wavelength around 375‒400 nm, and the absorption by the ZC NSs is seven to ten times greater than that by the ZC0. The enhanced absorption by ZC NSs is attributable to the carbon-black NPs. Based on the absorption data, the optical band gaps of...
Zinc oxide (ZnO) nanoparticles have been prepared from Anoectochilus elatus and characterized using absorption, vibrational and electron microscope analysis. They were carried for antibacterial, inflammatory control tendency, and potential antioxidant activities. The brine shrimp lethal assay tested the ...
Zinc oxide is an essential ingredient of many enzymes, sun screens, and ointments for pain and itch relief. Its microcrystals are very efficient light abso
