| Abstract Scope |
Transparent polycrystalline ceramics have been developed for various scintillation applications including nuclear nonproliferation and medical imaging. Successful synthesis of these transparent ceramics may be influenced by precursor particle size and morphology. High entropy oxides show promise in enhancing functional properties of scintillating materials; however, the high entropy nature requires special considerations to synthesize homogeneous powders. In this work, high entropy rare earth aluminum garnet precursor powders are synthesized by a relatively fast, low cost, and low temperature aqueous synthesis method where polymer choice and quantity are varied to study the effects on the precursor powders. We find through X-ray diffraction measurements that polymer choice affects phase formation. Through scanning electron microscopy measurements, we find that powders synthesized with higher quantities of the polymer yield submicron particles that appear promising for densification into transparent ceramics. |
