Investigation of the electronic and structural phase transitions in TiSe2 and Eu doped BaTiO3

Abstract

When the light interacts with matter, various phenomena, such as absorption, reflection, transmission, refraction, scattering and so on occur according to the crystal structure and properties of the materials. The study of interaction of light with the materials helps to perceive important information about the electronic and structural properties. Spectroscopy is the technique which makes use of the interactions of electromagnetic radiation with matter, to determine the chemical and physical nature of the material under study. The intensity of the output radiation as a function of wavelength, frequency, or energy is called the spectrum hence the name Spectroscopy [1].
