| 摘 要： | Based on our previous discovery [Chem.Phys.Lett.325(2000)420] of the solid-state cathodoluminescence from organic luminescent materials in inorganic/organic heterojunction,we study characteristics of this new kind of electric-field-induced luminesecence by means of examining its oscillogram.We prepared three devices with differect structures in which PPV was used as luminescent layer,and SiO2 was used as accelerating layer.The experimental results might be understood only by means of the existence of solid-state cathodoluminescence.This new kind of luminescence makes it possible to produce new type of flat panel display.
