Fluorochlorozirconate Glass Ceramics For Photovoltaic And Computed Radiography Applications, Russell Lee Leonard

Doctoral Dissertations

Fluorochlorozirconate (FCZ) glass ceramics are versatile materials whose optical properties may be tuned through compositional or processing changes. For this work, FCZ glasses were synthesized, and then subsequently heat treated to create optically-active glass ceramics. The glasses and glass ceramics were characterized using a number of methods including differential scanning calorimetry, phosphorimetry, x-ray diffraction, and spectrophotometry. Samples were evaluated for applications in photovoltaics and computed radiography–especially those pertaining to intraoral dental radiography and portal imaging.

An Investigation Of Rare Earth Co-Doping In Fluorochlorozirconate Glass-Ceramic Imaging Plates To Improve The Storage Phosphor Properties For Computed Radiography, Sharon Gray

Masters Theses

Computed radiography is a standard medical imaging technology that uses photostimulable storage phosphor imaging plates to create an image. X-rays create electron hole pairs within the plate which recombine upon stimulation by a laser, producing light which is read out and stored as a digital image. Modern imaging plates contain an active layer of crystalline storage phosphors embedded in a polymer binder. The resolution of images from these plates is reduced due to light scattering at grain boundaries during readout. Fluorochlorozirconate (FCZ) glass-ceramic imaging plates containing BaCl₂:Eu²⁺ [barium chloride] [europium]nanocrystals in the orthorhombic phase have been developed …
