摘　　要：以提高等离子体放电效率为目标,采用实验测试的方法研究了不同介质层的介电常数和厚度对着火电压、静态margin、放电效率和真空紫外辐射的影响。结果表明,适当的增加介质层参数εr/d,虽然提高了放电过程中产生的能量损失,但其同时也可以有效增强阴极区的电场和电子温度,使得放电产生的分子态VUV强度大幅上升进而带来放电发光效率的提高。因此,优化介质层参数可以作为今后提高等离子体放电效率的有效途径之一。Herein,we reported the optimization of ACC-plasma display panel. The effect of the relative permittivity（εr） and thickness（d） of the dielectric layer on the discharge properties,including the firing voltage,static margin,luminous efficacy and vacuum ultra-violet（VUV） emission was investigated with the lab-built test platform equipped with intensified charge coupled device video camera and spectrometer. The results show that the εr/d ratio of the dielectric layer had a major impact. To be specific,as the εr/d ratio increased,the electric field and electron temperature in cathode region increased; and the intensity of VUV emission from the discharge-produced excimers sharply increased,resulting in a significant increase of the luminous efficacy,in spite of the increasing energy loss in the discharge.
