采用溶胶-凝胶法在BaMgAl 10 O 17：Eu 2+（BAM）荧光粉表面包覆一层Co掺杂的Al 2 O3着色层。控制涂层以产生几纳米厚的薄的连续膜。钴的引入增加了该层的着色。该涂层提供了多种效果，例如增强的耐久性、改善的发射颜色和降低的反射率。这些变化将导致显示设备的寿命延长、色域更宽和环境对比度更高。该涂层不仅用作损伤保护层，而且还用作滤色器。
BaMgAl10O17:Eu2+(BAM) phosphor was encapsulated with a cobalt-doped Al2O3colored layer by the sol-gel process. The coating layer was controlled to result in a thin continuous film several nanometers thick. Introduction of cobalt added coloration to the layer. This coating provided multi-effects such as enhanced durability, improved emission color, and reduced reflectance. These changes will result in improved longevity, wider color gamut and higher ambient contrast ratio of display devices. The coating layer acts not only as a damage protection layer but also as a color filter.
