摘　　要：采用丝网印刷法在PDP的传统Mg O保护层上制备了六硼化镧薄膜。改变工艺参数,测试了La B6/Mg O薄膜的表面形貌和光学性能,并对透明的La B6/Mg O薄膜在Xe/Ne混合气体中的放电性能进行了测试。实验结果表明,采用400目丝网和球磨后的La B6粉末有利于提高La B6/Mg O薄膜的透过率,相比于原有的Mg O衬底,透过率达到90%以上。放电测试结果表明,印刷了La B6薄膜的Mg O+La B6样品的放电性能优于传统的Mg O保护层,其中着火电压降低了7%左右,放电延迟降低了9%左右。The La B6 thin film was deposited on Mg O protective layer of PDP by the screen-printing method. The surface appearance and the optical performance of La B6/ Mg O films fabricated with different process parameters were tested. Besides,the discharge performance of the La B6/ Mg O film with high transmittance was tested in Xe / Ne mixed gases. It is shown that the screen of 400 meshes and the ball-milled La B6 are benefit to improve the visible light transmittance. Using the conventional Mg O protective layers as a reference,the visible light transmittance of La B6/ Mg O film reaches at a high level of 90%. The consequence of the discharge test has shown that the discharge performance of the Mg O substrate printed with the La B6 thin film is better than the traditional Mg O protective layer.The firing voltage and discharge delay time have been descended by 7% and 9%,respectively.
