摘要

用spindt型Mo FEAs研究了有机薄膜的发光。在本研究中，我们研究了有机薄膜作为发射层的发射机理。发射特性取决于器件结构。在单层Alq3薄膜中观察到扩散发射。在双层TPD/Alq3薄膜中，在Alq3层较厚的情况下也观察到扩散发射。TPD/Alq3结构的发射效率高于单层结构。为了解释这些实验结果，讨论了扩散发射模型和发射机理。

Study on luminescence of organic thin films using field emitter arrays

The luminescence of organic thin films using Spindt-type Mo FEAs has been studied. In this study, we investigate an emission mechanism of organic thin films as emission layer. Emission characteristics were dependent on the device structure. Spread emission was observed in single-layered Alq3 films. In double-layered TPD/Alq3 films, the spread emission was also observed in the case of a thick Alq3 layer. Emission efficiency of the TPD/Alq3 structure was higher than that of the single-layered one. To explain these experimental results, models of the spread emission and emission mechanisms are discussed.
