摘　　要：制备了三种结构的薄膜电致发光器件 ,以PPV作为发光层 ,SiO2 作加速层 ,证明了固态类阴极射线发光的存在 ,对其发光动力学中的一些问题进行了研究 。Solid state analogy cathodoluminescence is a new kind of cathodoluminescence happening not in vacuum but in solid state materials like SiO 2 with the properties of semiconductor.In our experiments,we selected the solid state material SiO 2 as acceleration layer.The accelerated electrons with excite directly the luminescence materials in adjacent luminescent layer just like cathodoluminescence.The difference from cathodoluminescence lies in that the energetic electrons are accelerated not in vacuum but in solids.We prepared three devices of thin film electroluminescence with different structures.The phosphors layer is PPV and the accelerating layer is SiO 2 in these structures.Solid state analyogy cathodoluminescence was found in these devices and the luminous dynamics of it was studies also.We prepared the existence of solid state analogy cathodoluminescence in our experiments.And the efficiency of devices with this kind of new structure has been improved compared with the of formal experiments without solid state analyogy cathodoluminescence.This new phenomenon of luminescence makes it possible to set up a new type of flat display technology.
