如此薄的LiF不足以保护活性层在蒸镀金属电极时免受高温金属原子的破坏，也不能有效地阻挡氧气和水分子扩散进入活性层。

Such a thin layer of LiF cannot efficiently protect the underlying active layer from damage during the evaporation of hot cathode metal atoms , and also cannot provide sufficient protection against the diffusion of oxygen and water .

其次，考虑到LiF可以延缓氧分子扩散进入活性层，我们希望阴极修饰层中包含更多的LiF，同时还不影响修饰层的良好导电性。

Secondly , considering that LiF can retard the diffusion of oxygen into the active materials , we expect a very thick LiF in the cathode buffer layer , and simultaneously ensure that the buffer layer possesses a good electrical conductivity .
