Description
Summary:The exploration of alternative transparent electrodes to indium tin oxide (ITO) in organic light‐emitting diodes (OLEDs) has been a topic of interest. Among various candidates, ultrathin and continuous metal films have garnered significant interest for their ability to offer both transparency and conductivity. However, due to the higher surface energy of metals compared to substrates, metal films tend to grow in a discrete island shape, resulting in poor conductivity and even low transparency due to a localized surface plasmon by metal islands. In this work, a way to produce homogeneous ultrathin and continuous Ag film (UCAF) achieved through primary NF 3 plasma treatment on a glass substrate is proposed. This treatment introduces F bonds on the surface, enhancing the hydrophilicity of the glass surface and facilitating the formation of UCAF with high optical transmittance (>70%) and low sheet resistance (
