Implementation of Deep Ultraviolet Raman Spectroscopy

Ph. D. Thesis Chuan Liu 28th of December, 2011, Technical University of Denmark, Kgs. Lyngby Fluorescence interference is an important limitation in Raman spectroscopy. This problem can be avoided when the wavelength of the exciting light source is in the range of deep ultraviolet (DUV). DUV Raman spectroscopy expands the application field of Raman scattering technology, especially in catalysis, biological … Read More

Magneto-Optical Study of Defect Induced Sharp Photoluminescence in LaAlO3 and SrTiO3

Strongly correlated electronic systems such as Transition Metal Oxides often possess various mid-gap states originating from intrinsic defects in these materials. In this paper, we investigate an extremely sharp Photoluminescence (PL) transition originating from such defect states in two widely used perovskites, LaAlO3 and SrTiO3. A detailed study of the PL as a function of temperature and magnetic field has … Read More
