| 中文摘要: |
| 蓝色激光激发荧光材料获得白光的照明技术以其亮度高、体积小、照射距离远等优势而引起了广泛关注。然而，制备兼具高显色指数与高光通量的荧光材料仍然是一个挑战。基于此，本研究制备了一种由Y3Al3Ga2O12:Ce3+(YAGG:Ce3+)荧光玻璃和CaAlSiN3:Eu2+(CASN:Eu2+)荧光玻璃叠加而成的复合荧光玻璃。YAGG:Ce3+荧光玻璃的内量子效率高达90.9%，为原始荧光粉的98.15%。此外，它还具有优异的热稳定性，在150 ℃下保持室温发光强度的94.83%。经优选复合荧光玻璃中YAGG:Ce3+/CASN:Eu2+的比例，当6 wt%YAGG:Ce3+荧光玻璃与5 wt%CASN:Eu2+荧光玻璃复合时，获得了最高的显色指数90.1，光通量为1335.8 lm，实现了荧光玻璃基白光LD器件的高显色指数与高光通量的发光。因此，同质结构复合的荧光玻璃被视为一种有潜力的荧光转换材料。 |
| 英文摘要: |
| The illumination technology, which utilizes blue lasers to excite phosphor materials to produce white light, has garnered widespread attention due to its high brightness, compact size, and extended illumination range. Nonetheless, synthesizing phosphor materials with both high color rendering index(CRI) and high luminous flux(LF) remains a challenge. Based on this, a composite phosphor in glass(PIG) constructed by stacking Y3Al3Ga2O12: Ce3+(YAGG: Ce3+) PIG and CaAlSiN3: Eu2+(CASN: Eu2+) PIG was prepared. The internal quantum efficiency(IQE) of YAGG: Ce3+ PIG reaches 90.9%, representing 98.15% of the original phosphor powder. Furthermore, it exhibits outstanding thermal stability, retaining 94.83% of its room temperature luminescence intensity at 150 ℃. By selecting the ratio of YAGG: Ce3+/CASN: Eu2+ in composite PIG, the highest CRI of 90.1 and LF of 1335.8 lm were obtained when 6 wt%YAGG: Ce3+ PIG was combined with 5 wt%CASN: Eu2+ PIG, thereby realizing high CRI and LF in PIG-based white light LD devices. Therefore, the homogeneous structured composite PIG is regarded as a promising phosphor conversion material. |
