R Saravanan Non-Linear Optical Materials

Annotation

Non-linear optical materials have widespread and promising applications, but the efforts to understand the local structure, electron density distribution and bonding is still lacking. The present work explores the structural details, the electron density distribution and the local bond length distribution of some non-linear optical materials. It also gives estimation of the optical band gap, the particle size, crystallite size, and the elemental composition from UV-Visible analysis, SEM, XRD and EDS of some non-linear optical materials respectively. Keywords: Non-linear optical materials, Powder X-ray diffraction, UV-Visible spectroscopy, Scanning electron microscopy, Energy dispersive X-ray spectroscopy, Electron density distribution, Sample preparation, Pair distribution function, Atomic correlation function.
