The characterization of reservoir fracture networks is important in the development of geothermal power. Ion-based tracers studies can be used to elucidate the extent and connectivity of these fracture networks. Collecting real-time down-hole tracer data requires the development of novel ion detecting sensors. These detectors must survive the high brine levels, high temperature, high pressure, and other caustic environmental conditions encountered in these deep-hole wells. Several detectors are being pursued for this application, with our efforts have focused on developing fluorine ion selective electrodes. One proposed material for this is LaF3. While this compound is commercially available, we have developed several novel precursors in order to allow production of LaF3 nanomaterials, which are of interest due to their high surface area. The synthesis and characterization of a series of lanthanide trifluoroacetates and hexafluoro iso-propoxide derivatives as well as their conversion to the subsequent nanomaterials will be presented.Sandia National Laboratories is a multi-program laboratory managed and operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation, for the U.S. Department of Energy's National Nuclear Security Administration under contract DE-AC04-94AL85000
