Abstract
In a UV-Vis (ultraviolet-visible light) spectroscopic measurement, light absorption as a function of wavelength provides information about electronic transitions occurring in the material. For semiconductors, UV-Vis spectroscopy offers a convenient method of estimating the optical band gap, since it probes electronic transitions between the valence band and the conduction band. Transmission UV-Vis, Diffuse Reflectance UV-Vis, and Absorption UV-Vis configurations are discussed.
