Mechanochemical synthesis of nanocrystalline BaFCl:Sm3+ storage phosphor by ball milling

- Mechano-chemical synthesis of nanocrystalline BaFX:RE2+/3+ X-ray storage phosphors in the solid state.
- Photoluminescence and cathodoluminescence of Sm2+/3+.
- Observation of reduction of Sm3+ to Sm2+ upon ball-milling.
- X-ray storage properties based on Sm3+ to Sm2+ reduction.
