摘要: 半导体超晶格材料由于其特殊的光电性质引起人们的关注,So和Tokito等人用分子束沉积的方式制备了有机及有机无机复合的超晶格材料器件,但分子沉积中有机小分子染料的结晶影响薄膜的质量及器件的寿命。最近,我们用两亲性聚合物分子成功地将有机染料分子组装在聚合物LB膜中,有效地限制有机小分子染料结晶,实验证明此多层LB膜具有超晶格结构和较好的稳定性及发光特性。

Abstract: The dye TPB molecules were successfully fabricated into the polymer ESfilms with superlattice structure. The periodical structure of the multilayer films was determined by small angle X-ray diffraction, the period of 5. 8 nm was calculated according to the Bragg equation. It indicated that each periodical structure consists of two layers of LBfilms and the multilayer films have well ordered layer structure. The PLand ELspectra of the polymer/ dye multilayer films showed that the emission peaks of PLand ELshifted to short wave length relative to its bulk material due to the excitons confinement effects.

Key words: Superlattice, Photoluminescence, Electroluminescence, LB film
