For the liquid phase method , it is discovered that the optimal encapsulation is obtained at stalling ph equal 8 . 5 by the analysis of the influence of ph on the compactness . for the atmospheric chemical vapor deposition , the optimal experimental condition of coating is determined by the analysis of the influence of different reaction temperature and different flow rate of o2 and different reaction time on the compactness of the coating and the luminescent performance of the phosphor in the experimental scope 对于液相包膜，通过分析陈化ph值对膜层致密性能的影响，发现在ph值为8 . 5陈化能够得到最佳的包覆；对于化学气相沉积法，通过分析不同温度、不同氧流速、不同时间对包覆膜层致密性能和zns ： cu材料的发光性能的影响，找到了该实验范围内包覆的最佳条件。
