摘要
在有机发光二极管(OLED)器件衬底上制备可传递三维立体微结构可有效消除波导、增加出光耦合,从而增加器件出光效率。纳米压印技术是制备立体微结构的主要方法之一。采用紫外纳米压印技术在OLED衬底上制备三维立体微结构。首先采用电子束光刻(EBL)技术与干法刻蚀相结合的方法来制备高精度的紫外纳米压印模板;然后对模板进行清洗与抗粘连处理;最后采用紫外纳米压印技术在OLED衬底上成功制备了可传递三维立体微结构。制备结果表明,所形成的微结构具有均匀性好和压印精度高的特点。
By fabricating the transferable three-dimensional microstructure on the substrate of the organic light emitting diode （OLED）, the waveguide is eliminated and the optical coupling is en- hanced effectively, then the luminous efficiency of the OLED is increased. The nanoimprint tech- nology is one of the main methods to fabricate the three-dimensional microstructure. The three- dimensional microstructure was fabricated on the OLED substrate with the UV nanoimprinting technology. Firstly, the UV nanoimprinting template with high-precision was fabricated using the method of the electron-beam lithography combined with the dry etching. Then, the cleaning and anti-stick treatment were carried out on the template. Finally, the transferable three-dimen- sional microstrueture was fabricated successfully on the （）LED substrate with the UV nanoim- print technology. The results show that the fabricated microstructure has the advantages of good uniformity and high imprint precision.
