中文摘要：
采用有机磷光材料三-（2-苯基吡啶）-铱（Ir（PPY）3）与无机材料SiO2复合制成夹层结构器件，用交流电压驱动获得了Ir（PPY）3主峰位于517nm的发光和主峰位于435nm的蓝色发光．通过分析器件的光谱特性，发现这两个发光峰都是源于SiO2中加速电子直接碰撞激发有机层引起的固态阴极射线发光．继实现多种有机聚合物材料和有机小分子材料八羟基喹啉铝（Alq3）的固体阴极射线发光之后，又证实了有机磷光材料的固态阴极射线发光．
英文摘要：
The devices with sandwiched structure are prepared by compounding tris （2-phenylpyridine） iridium （Ir（PPY）3 ） with SiO2 . The green emission of Ir（PPY）3 at 517 nm and blue electroluminescence at 435 nm are obtained from the devices under AC voltage. Both the green and the blue emission are attributed to the solid-state cathodoluminescence （SSCL） of Ir（PPY）3 excited by hot electrons which are accelerated in SiO2. Phosphorescent SSCL is confirmed after the realization of SSCL on organic polymers and organic small molecules tris-（8-quinolinolato）aluminum （Alq3）.
