... same spectral characteristics as X. Addition of progressively increasing amounts of NaOMe (> 2 molar equivalents) leads to the replacement of the absorption due to Y by a new absorption band with maxima at 344 and 510 nm. The new maxima are attributed to the formation of a new absorbing species, Z, ...

... TiO2 and ZnO NPs were spin-coated, and the CdSe quantum dots (QDs) were drop-cast. ZnO nanowires and films were grown on glass cover slips by chemical bath deposition from zinc nitrate and methenamine [4]. After three hours, nanowires have lengths of ~1 μm and diameters of 50-100 nm. It is possible ...

Ultraviolet–visible spectroscopy
Ultraviolet–visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. This means it uses light in the visible and adjacent (near-UV and near-infrared [NIR]) ranges. The absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved. In this region of the electromagnetic spectrum, molecules undergo electronic transitions. This technique is complementary to fluorescence spectroscopy, in that fluorescence deals with transitions from the excited state to the ground state, while absorption measures transitions from the ground state to the excited state.
