摘要

提出了一种通过在玻璃衬底表面引入氧化银种子层的方法，成功制备了具有良好表面、光学、电学特性的超薄透明导电Ag薄膜。首先，在玻璃衬底上用热沉积的方法生长1 nm Ag薄膜，然后对该薄膜进行空气等离子体处理，生成氧化银种子层，该种子层可抑制Ag原子的随机迁移，提高随后沉积Ag原子成核密度，从而促进Ag原子快速成膜。以该超薄透明氧化银/银薄膜为阳极，实现了一种高效磷光有机电致发光器件，器件的最大电流效率、功率效率分别为60.4 cd·A

和63.2 lm·W

，是常规ITO器件的1.45倍和1.60倍。该研究结果表明，以氧化银为种子层的超薄透明Ag薄膜是极具发展潜力的透明导电电极。

Abstract

This paper proposes a strategy to successfully realize ultra-thin transparent conductive Ag thin films with excellent surface， optical， and electrical properties by introducing a silver oxide seed layer onto the surface of a glass substrate. Firstly， a 1-nm-thick Ag film is evaporated onto a glass substrate by thermal deposition and then treated with oxygen plasma to generate a silver oxide seed layer. The seed layer can alleviate the random migration of Ag atoms and improve the nucleation density of the subsequently deposited Ag atoms， thus promoting the film formation of Ag atoms. An efficient phosphorescent organic light-emitting device was fabricated using the realized ultra-thin transparent silver oxide/silver film as an anode. The device's maximum current efficiency and power efficiency are 60.4 cd·A

-1

and 63.2 lm·W

-1

， respectively， 1.45 and 1.60 times higher than those of the conventional ITO-based devices. The results show that the ultra-thin transparent Ag thin film with silver oxide as a seed layer is a highly promising transparent conductive electrode.
