Optimizing The Performance Of A Glass-Ceramic Storage Phosphor As An Imaging Plate For Medical Use, Manh Vu

Masters Theses

Europium-doped-fluorochlorozirconate glass ceramics, known as ZBLAN, were produced in a glove box which has a controlled environment of argon gas. For imaging applications BaCl₂ is used instead of BaF₂. Their properties after different thermal processing and different amounts of europium-doping were investigated. After annealing the ZBLAN glass, BaCl₂ nanoparticles are precipitated in the glass matrix. These glass ceramic storage phosphors are strong candidates for replacing traditional x-ray screen film system and commercial storage phosphors such as Agfa MD-30.

Differential scanning calorimetry (DSC) was used to determine the crystallization temperature of the hexagonal phase of BaCl_{2 …}
