We investigated the characteristics of MgO surface with MgO nanocrystal powders due to the longterm (500 hours) ion bombardment comparing with the conventional MgO surface in this study. When the MgO nanocrystal powders were coated on the conventional MgO surface, it was observed that the sputtered Mg particles from MgO surface were re-deposited on the MgO nanocrystal powders, which was able to significantly suppress the re-crystallization on the phosphor layers. We confirm that the MgO nanocrystal powders play a significant role in suppressing the degradation of the MgO surface and phosphor layer after long-term severe ion bombardments. Accordingly, when the MgO nanocrystal powers were applied to the conventional MgO surface, the variations of discharge characteristics, such as address discharge delay time, firing voltage of sustain and address discharge, and luminance, were significantly reduced comparing with the conventional MgO surface.
在本研究中，我们通过与传统氧化镁表面进行比较，研究了经过长期（500小时）离子轰击的氧化镁纳米晶粉末的氧化镁表面特性。当将氧化镁纳米晶粉末涂覆在传统氧化镁表面时，观察到从氧化镁表面溅射的镁颗粒重新沉积在氧化镁纳米晶粉末上，这能够显著抑制荧光粉层上的再结晶。我们证实，在长期严重离子轰击后，氧化镁纳米晶粉末在抑制氧化镁表面和荧光粉层的降解方面发挥了重要作用。因此，当将氧化镁纳米晶粉末应用于传统氧化镁表面时，与传统氧化镁表面相比，诸如寻址放电延迟时间、维持和寻址放电的点火电压以及亮度等放电特性的变化显著减小。
