High energy ball milled iodoapatite in the form of an amorphous matrix embedded with nanocrystals can be readily crystallized by subsequent low temperature thermal annealing, which greatly improves the thermal stability and iodine confinement.

LiTaO3: Tm3+, Yb3+powders were synthesized by a high-energy ball-milling (HEB) method compared with the conventional solid-state reaction (SSR) method. Under the excitation of 980 nm laser, the strong blue emission (477 nm) band is observed and attributed to1G4-3H6of Tm3+. Because of it causing high local temperature and narrow particles size, increasing the contact area between the particles and improved crystallinity of the host, synthesis by high-energy ball milling show higher photoluminescence (PL) intensity compared to the solid state reaction method. In the process of mechanical milling, Tm3+, Yb3+co-doped LiTaO3phosphors with high photoluminescence property could be achieved at a relatively low reaction temperature.
