Photoluminescence of Zn5(CO3)2(OH)6 nanoparticles synthesized by utilizing CO2 and ZnO water slurry

Plasmonic Nanocomposites of ZnO-Ag Produced by Laser Ablation and Their Photocatalytic Destruction of Rhodamine, Tetracycline and Phenol

“…This is owing to the presence of defects of different nature, most of which are related to oxygen vacancies and to interstitial zinc both in its ground and ionic states [46,47]. The absorption of zinc hydroxycarbonate is known to lie far in the UV range (Eg = 5.5 eV) and does not affect the absorption band edge of ZnO [48]. ALT of the colloid was found to have no significant effect on its absorption spectrum.…”

Chiral mesostructured hydroxide zinc carbonate for enantioseparation in high performance liquid chromatography

“…2a shows the DRUV-Vis and mirror-imaged DRCD spectra of antipodal CMHZC@S. Taking l -CMHZC@S as an example, a negative exciton coupling centered at 205 nm and a negative shoulder at 215–380 nm could be observed from the DRCD spectrum, which coincides with the DRUV-Vis absorbance attributed to the overlap of various HZC characteristic absorption bands. The absorption in the 190–215 nm range could correspond to the n–π and π–π* electron transitions of carbonate; 28 the bands at 215–380 nm would be attributed to the charge transfer of C 2p–O 2p → O 2p–H 1s–Zn 3d, 29 which mainly compose the electron transition from the conductor band bottom to the valence band top instead of the organic residues (Fig. S9, ESI†).…”
