UV–Vis Spectrum

UV–Vis Spectrum

When light passes through a substance, a portion of the light is absorbed while the remaining light is reflected or transmitted. If the molecule absorbs light between the wavelengths of 180–400 nm range, the UV spectrum is obtained, and if it absorbs light in the 400–780 nm wavelength range, the visible spectrum is obtained.
The UV–Vis spectrum of a molecule is the plot of its absorbance versus wavelength. The plot is drawn by taking molar...

UV–Vis Spectroscopy: Beer–Lambert Law

UV–Vis Spectroscopy: Beer–Lambert Law

The Beer-Lambert law describes the relationship between absorbance and concentration, which combines the principles established by scientists Johann Heinrich Lambert and August Beer. Lambert's law states that when light passes through a medium, the loss in intensity is directly proportional to the original intensity and the path length of the light. Beer's law proposed that the transmittance of a solution remains constant if the product of concentration and path length is constant. The modern...

Background:

Ellipsometry is a valuable technique for surface and thin-film analysis due to its ease of sample preparation and measurement.
Traditional data analysis for ellipsometry often requires specialized numerical methods and can be challenging, with unsolved problems in data interpretation.
Existing methods for determining film properties from ellipsometer data frequently necessitate a priori knowledge of the film's characteristics.

Purpose of the Study:

To present an alternative computational method for analyzing ellipsometer data.
To determine the thickness and optical properties of an absorbing film on a known substrate.
To overcome the limitations of existing data analysis techniques by reducing the need for prior film information.
