  • New luminescent materials and high-performance solution-processed oxide thin films

    Creator:
    Jiang, Kai
    Abstract:
    Crystals of an incongruent-melting compound, Ba₃MgSi₂O₈, were grown by the flux method and its structure was determined by single crystal X-ray diffraction methods. Ba₃MgSi₂O₈ crystallizes in trigonal space group P-3[bar]m1 with a = 5.6123(3) Å, c = 7.2667(9) Å and Z = 1. Eu²⁺ ions prefer one crystallographic Ba site...

  • Structure-property relationships in oxides containing tellurium

    Creator:
    Siritanon, Theeranun
    Abstract:
    Oxides of post-transition metals often show unique structures and properties due to the presence of lone pair electrons and the diffused s orbitals. The present work focuses on synthesis and characterizations of oxides containing Te, a heavy post transition metal. New series of pyrochlore oxides of the formula Cs(M,Te)₂O₆ (M...

  • Exploratory Studies Within the Exotic Lyonsite Structure

    Creator:
    Tang, Joseph N.
    Abstract:
    Structure-property relationships have always underpinned the field of solid state chemistry; dependable structural descriptions are integral to understanding and controlling the physical properties of inorganic compounds old and new. While a handful of crystal structures are celebrated for their versatility, flexibility, and functionality, the existence of more exotic structures is...

  • Development of new high-temperature piezoelectric perovskite ceramics

    Creator:
    Ansell, Troy Youngmin
    Abstract:
    Lead zirconate titanate (PZT) is the dominant ferroelectric material in the market due to its excellent piezoelectric properties, relatively high Curie transition temperature (T[subscript C]), low cost, etc. However, because of emerging applications with requirements for high temperature (T[subscript C] > 400 °C) ferroelectrics, researchers are increasingly looking at alternative...

  • Excited state molecular structural evolution and chemical reactivity studied by femtosecond stimulated Raman spectroscopy

    Creator:
    Han, Fangyuan
    Abstract:
    In this dissertation, my research work on excited state dynamics of small organic molecules in solutions is presented. Using femtosecond stimulated Raman spectroscopy (FSRS) as the main experimental tool, the excited state hydrogen-bonding dynamics (ESHBD) of Coumarin 102, a common laser dye molecule, in ethanol solution is examined with <150...
