摘要:

照明一直是我國能源領域的消費大戶，尋找高效健康的白光光源一直是照明行業的重要任務。有機發光二極管（OLED）自1987年被柯達公司的鄧青云博士提出以來，經過了數十年的發展目前已經在小尺寸顯示領域得到了廣泛的應用和市場的認可。在照明領域，白光有機發光二極管（WOLED）也以其高性能、可彎曲、面光源、無藍害等一系列優勢受到人們越來越多的重視，是未來新型固態照明光源的有力競爭者。隨著OLED技術的深入發展，WOLED近年來已經得到了理論、技術、應用等多方面發展，而且取得了重要成果。綜述了近期WOLED的設計方法、主要進展以及所面臨的問題，主要從全熒光WOLED、全磷光WOLED和雜化WOLED三種器件構筑方法對WOLED進行了概述。

Abstract:

The lighting industry is always a major consumer in China’s energy sector. Finding efficient and healthy white light sources has always been an important task in the lighting industry. Since the introduction of Dr. CW Tang from Kodak in 1987, organic light-emitting diodes (OLEDs) have been widely used in the field of small-size displays and approved by the market after decades of development. In the field of lighting, white organic light-emitting diodes (WOLEDs), strong competitor for new solid-state lighting sources in the future, are also receiving more and more attention for their high performance, flexibility, surface light source, and blue-damage-free. With the in-depth development of OLED technology, white organic light-emitting diodes have been developed in many aspects in theory, technology, application, etc., and have achieved many important results. This paper reviews the recent design methods, major developments, and problems faced by white organic semiconductors. In this paper, white organic light-emitting diodes are mainly summarized from three kinds of device construction methods: full-fluorescence WOLEDs, all-phosphor WOLEDs, and hybrid WOLEDs.
