Abstract

The potential of organic semiconductor based devices for light generation is demonstrated by the commercialisation of display technologies using organic light emitting diode (OLED). In OLED, organic materials plays an important role of emitting light once the current is passed through. However OLED have drawbacks whereby it suffers from photon loss and exciton quenching. Organic light emitting transistor (OLET) emerged as a new technology to compensate the efficiency and brightness loss encountered in OLED. The structure has combinational capability to switch the electronic signal such as the field effect transistor (FET) as well as to generate light. Different colours of light could be generated by using different types of organic material. The light emission could also be tuned and scanned in OLET. The studies carried out in this paper focuses on investigation of fabricated MEH-PPV based OLED and also OLET via current voltage characteristics. These studies will continue with a view to develop an optimised MEH-PPV based OLET.

摘要

基于有机半导体的器件在光产生方面具有很大的潜力，这一点已经被使用有机发光二极管（OLED）的显示技术的商业化所证明。在 OLED 中，一旦电流通过，有机材料就会起到发光的重要作用。然而，OLED 也存在一些缺点，例如光子损失和激子猝灭。有机发光晶体管（OLET）作为一种新技术出现，以弥补 OLED 中遇到的效率和亮度损失。该结构具有组合能力，可以切换电子信号，如场效应晶体管（FET），同时也可以产生光。通过使用不同类型的有机材料，可以产生不同颜色的光。在 OLET 中，光发射也可以进行调谐和扫描。本文的研究重点是通过电流电压特性来研究基于 MEH-PPV 的 OLED 和 OLET 的制备。这些研究将继续进行，以开发优化的基于 MEH-PPV 的 OLET。
