摘要

电致发光材料在大屏幕平板显示和移动通讯器件方面有着极大的优越性。Ⅱ-Ⅵ族无机半导体、金属有机化合物及共轭聚合物等都是电致发光材料。由半导体纳米晶体和电致发光聚合物组成的双发光器件中，纳米半导体的发光不仅可以通过掺杂及形成核壳结构来加以调节，而且受到其复合体系类型、纳晶含量、外加电压等因素制约；而无机半导体的高电荷输运特性也将影响聚合物发光层的效率。同时，利用无机纳米半导体的光导特性，这种复合体系也可以制成光导与电致发光双功能器件，且其发光效率可有较大幅度提高。

Abstract

Electroluminescent materials

involving inorganic semiconductors like Ⅱ-Ⅵ compounds

metallorganic compounds and conjugated polymers

have many advantages in mobile communication and large plane display devices.In the dual emitting devices containing semiconductor nanocrystals and electroluminescent polymers

the emitting wavelength could not only be adjusted by doping or by forming core-shell structure

but also depend upon the content in the system and the applied voltage.The inorganic semiconductors with high-charge transporting abilities could affect the emission efficiency of the polymer emitter.Dual functions can also be achieved with high emission efficiency by benefiting from the photoconduction of the semiconductor nanocrystal and the electroluminescence of the polymer.
