| Popis: | Large micron-sized Y3Al5O12:Ce3+ phosphors were successfully synthesized by a cost-effective method using eutectic mixtures of YF3–AlF3 as the molten-salt flux for high-power laser diodes applications. The crystallinity, morphology, particle size, thermal quenching properties of the phosphors were measured, respectively. The phosphor particle size increased with increasing amount of flux, and the medium size (D50) could reach 40 μm when adding 25 wt% YF3–AlF3. The phosphors with larger particle size did not only exhibit superior optical performances but also excellent thermal-quenching characteristics, leading to a lower surface temperature and a higher radiant efficiency when excited by a high-power laser. |
