Title: Studies on crystal growth of some pure and mixed rare-earth Fumarates and their characteristics.
Author: Shah, Mairaj ud Din (Scholar); Want, Basharat Ahmad (Guide)
Abstract: Crystal growth and its characterization has become valuable branch of science due to the growing demand of scientifically and technologically important crystals for different applications. Rare-earth based crystals of metal organic coordination compounds have an important role from both academic and technological point of view due to their outstanding physical, magnetic and luminescent properties. The compounds of rare-earths have also gained importance for their dielectric, ferroelectric, ferroelastic and conductivity behaviour. Due to the large applicability of rare-earth coordination compounds, it was thought worthwhile to investigate growth and characterization of tebium fumarate, gadolinium fumarate and mixed gadolinium-terbium fumarate heptahydrate single crystals for scientific investigations. The work presented in this thesis was carried out at the Solid-State Research Laboratory, Department of Physics, University of Kashmir, Srinagar. The thesis entitled “Studies on crystal growth of some pure and mixed rare-earth fumarates and their characteristics” is a comprehensive report on the growth of single crystals of terbium, gadolinium and mixed gadolinium-terbium fumarate heptahydrates in hydro silica gel and their detailed characterization. It also includes the results of dielectric, ac conductivity, thermal, luminescent and magnetic moment measurements of the grown crystals. The thesis is divided into two sections, Section-A pertaining to growth and characterization of crystals, consists of four chapters and section-B including the physical properties of as-grown crystals consists of five chapters.
