WebThe basic structural and optical properties of the prepared Mn:ZnS thin films were assessed through X-ray diffractometry, UV–Visible and photoluminescence spectroscopy. Two-photon induced nonlinearity in the Mn:ZnS thin films was estimated using the Z-scan technique. We have observed very high nonlinear absorption coefficient of 7.7 cm/W.
WebUV-vis spectroscopy is a cost-effective, simple, versatile, non-destructive, analytical technique suitable for a large spectrum of organic compounds and some inorganic species. As a function of wavelength, UV-vis spectrophotometers measure the absorption or transmission of light that passes through a medium. WebThe thickness of a single-layer film can be measured easily using a spectrophotometer. Note, however, that this is possible only for film thickness in a range of approximately 0.3 …
