采用机械力化学活化法成功制备了一种新型的Al 10 O3 N8：Eu 2+荧光粉。在高能球磨的帮助下，原料大部分转化为非晶相，在相对温和的反应条件下显著促进了Al 10 O3 N8相的合成。Al 10 O3 N8：Eu 2+荧光粉在紫外光激发和小的热猝灭下显示出较宽的蓝色发射带。此外，Al 10 O3 N8：Eu 2+荧光粉在147 nm激发下具有较强的蓝光发射，且衰减时间较BAM：Eu 2+荧光粉短，是一种很有潜力的等离子体显示屏用荧光粉。对Al 10 O3 N8：Eu 2+荧光粉进行了Si-N掺杂，进一步提高了其发光强度，并对其机理进行了探讨。因此，将该合成方法应用于其他难以实现的材料是可行的。
A novel Al10O3N8:Eu2+phosphor was prepared successfully by a mechanochemical activation route. With the help of high-energy ball milling, the starting materials were mostly transformed into an amorphous phase, which significantly promotes the synthesis of Al10O3N8phase at a relatively moderate reaction condition. Al10O3N8:Eu2+phosphor showed a broad blue emission band under ultraviolet-light excitation and small thermal quenching. Additionally, it was found that Al10O3N8:Eu2+phosphor showed a strong blue emission under 147 nm excitation and shorter decay time compared with BAM:Eu2+phosphor, making it a potential phosphor used in plasma display panels. Si–N doping was performed to further increase the luminescence intensity of Al10O3N8:Eu2+phosphor and the related mechanism was discussed. Prospectively, it was feasible to apply the synthesis approach to other hardly achieved materials.
