摘要

研究了新型镉配合物Cdmq2在电致发光器件中的稳定性和适用性。Cdmq2通过不同的表征技术进行表征。它具有优异的热稳定性，最高可达440°C。在390nm处观察到π - π*跃迁引起的吸收光谱最大值。利用该材料制备了有机发光二极管(OLED)。该器件的组成部分为ITO/α-NPD/Cdmq2/BCP/Alq3/LiF/Al。电致发光(EL)器件在23V电压下发出黄绿色的光，最大发光1185cd /m2。

A new cadmium complex material for yellowish-green light electroluminescent devices

The stability and applicability of new cadmium complex, Cdmq2, is investigated for electroluminescent device application. The Cdmq2 is characterised by different characterisation techniques. It shows excellent thermal stability up to 440 °C. A maximum is observed at 390 nm in absorption spectra which attributed to π - π* transition. Organic light emitting diode (OLED) has been fabricated using this material. The integral parts of the device were ITO/α-NPD/Cdmq2/BCP/Alq3/LiF/Al. Electroluminescence (EL) device emits yellowish green light with maximum luminescence 1185 cd/m2 at 23V.
