Design and synthesis of novel lanthanoid complexes for the fabrication of light emitting devices. There is a huge and still growing economy centred around the design and fabrication of low-cost Light Emitting Devices (LEDs), as demonstrated by the excess of US$1.3 billion invested in this field between 2000 and 2007. Nations focused on the production of new and more efficient materials will be at the forefront of these emerging technologies.

Summary
Design and synthesis of new radical and heterometallic magnetic molecules. This project aims to build upon recent advances in developing magnetic molecules for use in electronic devices. The development of new electronic devices based on quantum systems will lead to the development of faster more efficient computers.

This project aims to build upon recent advances in developing magnetic molecules for use in electronic devices. The development of new electronic devices based on quantum systems will lead to the development of faster more efficient computers. Magnetic molecules are promising candidates for the data storage components in these systems. Despite the potential of these materials, the temperature at which they operate needs to be increased above that of liquid helium. This project is focused on the development of new magnetic lanthanide molecules with higher working temperatures. The outcomes will provide a greater understanding of how structure impacts on the magnetic properties of the molecule.Read moreRead less
Illuminating hidden processes in emissive lanthanoid complexes. This project aims to understand the antenna effect used to sensitise lanthanoid luminescence. Despite their use in modern high-tech applications, from optical fibre amplifiers (telecommunications) to luminescent probes and sensors (biological imaging), understanding is largely based on speculation or generalised 'rules-of-thumb', severely limiting progress in the field. This project will research these processes, using chemical synt ....Illuminating hidden processes in emissive lanthanoid complexes. This project aims to understand the antenna effect used to sensitise lanthanoid luminescence. Despite their use in modern high-tech applications, from optical fibre amplifiers (telecommunications) to luminescent probes and sensors (biological imaging), understanding is largely based on speculation or generalised 'rules-of-thumb', severely limiting progress in the field. This project will research these processes, using chemical synthesis, theory and spectroscopic techniques. This is expected to lead to new emissive lanthanoid-based compounds using 'a priori' approaches, with better performance than current gold standards and references. Intellectual property created will lead to new commercial products, and to creation of new Australian based spin-off/start-up companies.Read moreRead less
Electronic and Optical Properties of Doped Titanium Dioxide. Titanium dioxide, is widely used as a white pigment, owing to its high refractive index, second, only after diamond. Yellowing of rutile pigment particles, observed on prolonged exposure to sunlight, is a serious problem that pigment manufacturers would like to overcome. It is proposed that aluminium-doping of rutile limits this discolouration by altering the electronic structure of the rutile particles. This project seeks to identify ....Electronic and Optical Properties of Doped Titanium Dioxide.

Yellowing of rutile pigment particles, observed on prolonged exposure to sunlight, is a serious problem that pigment manufacturers would like to overcome. It is proposed that aluminium-doping of rutile limits this discolouration by altering the electronic structure of the rutile particles. This project seeks to identify the specific electronic cause of the yellowing process, the nature of the Al defect,it's effect on the electronic structure of rutile, and the electronic perturbations that may occur when other dopants are used.Read moreRead less

The scientific benefits would flow, in the first instance, to the large national and international communities of scientists whose research makes use of the results of X-ray diffraction experiments. Applications of the research to amino acids and peptides will benefit investigations into the structure and molecular dynamics of biological systems, including proteins and enzymes. Studies of charge densities in crystals will obtain a standard tool for improved modelling of molecular motion, resulting in physically more realistic charge density functions, and hence greater insight into the relationship between properties of crystals and their constituent molecules.Read moreRead less
