Abstract Scope |
We explore a new concept in design of single crystal and polycrystalline ceramic scintillators for high-energy X-ray radiography. They are based on multi-component aluminum garnets which are solid solutions of several rare-earth elements taken in equiatomic proportions. We successfully grew single crystals via the micro-pulling down technique and used wet chemistry synthesis to produce powders that were subsequently hot pressed to produce high density bulk ceramics. The effect of the average ionic radii on phase formation, and optical and scintillation properties were investigated. |
