Here, the synthesis and characterization of high quality lanthanide fluorides is presented. In particular, this dissertation focuses on dysprosium fluoride doped with ytterbium, to eventually be used as a forensic and clandestine neutron detector material. There is a need for neutron detectors that have no sensitivity to any other type of radiation and can be used as a forensic tool to go back and look at an event. There is the further requirement that such detectors be hard to detect by those being monitored.
