“…Nevertheless, the anode thin film resistances mentioned above are all lower than the value of commercially available ITO, which is about 14 Ω/sq. This thin layer resistance is inversely proportional to the carrier mobility and conductivity, and the factors affecting the multilayer film conductivity include the thickness and surface roughness of the Ag layer [ 31 ]. It can be seen that, due to the thickness of the evaporated MoO 3 being 5 nm, the thin film resistance measured for ZnS/Ag/MoO 3 does not increase much compared with ZnS/Ag, so MoO 3 will not have a significant impact on the charge balance and electrical properties of OLEDs [ 32 ].…”

The structure used in this study is as follows: substrate/PMMA/ZnS/Ag/MoO3/NPB/Alq3/LiF/Al. Here, PMMA serves as the surface flattening layer, ZnS/Ag/MoO3 as the anode, NPB as the hole injection layer, Alq3 as the emitting layer, LiF as the electron injection layer, and aluminum as the cathode. The properties of the devices with different substrates were investigated using P4 and glass, developed in the laboratory, as well as commercially available PET. After film formation, P4 creates holes on the surface. The light field distribution of the device was calculated at wavelengths of 480 nm, 550 nm, and 620 nm using optical simulation. It was found that this microstructure contributes to light extraction. The maximum brightness, external quantum efficiency, and current efficiency of the device at a P4 thickness of 2.6 μm were 72,500 cd/m2, 1.69%, and 5.68 cd/A, respectively. However, the maximum brightness of the same structure with PET (130 μm) was 9500 cd/m2. The microstructure of the P4 substrate was found to contribute to the excellent device performance through analysis of the AFM surface morphology, film resistance, and optical simulation results. The holes formed by the P4 substrate were created solely by spin-coating the material and then placing it on a heating plate to dry, without any special processing. To confirm the reproducibility of the naturally formed holes, devices were fabricated again with three different emitting layer thicknesses. The maximum brightness, external quantum efficiency, and current efficiency of the device at an Alq3 thickness of 55 nm were 93,400 cd/m2, 1.7%, and 5.6 cd/A, respectively.

“…Silver is the most commonly used noble metal, due to its more suitable optical properties [7,8], which allow the coatings to remain transparent in the visible range, while achieving a high infrared reflectance. The transparent thin layers are essential for adjusting the optical properties (often acting as an anti-reflective effect, to maximize visible transmission), but they also serve other functions, such as acting as a seed layer to improve silver deposition and enhance adhesion, or protecting the silver layer from exposure to the atmosphere [9][10][11][12][13].…”

This research sought to determine the optimal conditions for depositing thin silver layers in the fabrication of low-emissivity coatings. The study utilized an in-line semi-industrial high-vacuum magnetron sputtering system with rectangular targets, closely resembling those used in industrial settings. Trilayer AZO/Ag/AZO structures were deposited to enhance the wetting properties of the silver, and to protect it from the atmosphere. The effects of the power and argon flow on the sample properties were analyzed, along with variations in the silver thickness. The results demonstrate that a lower power (200 W) and higher argon flows (1000 sccm) lead to a higher transmittance and a lower sheet resistance, resulting in a reduced emissivity (up to 0.015 for 24 nm of silver). The identified optimal conditions offer valuable recommendations for producing more efficient and optically superior coatings. This study also reveals the importance of the silver thickness to the properties of the coatings, in accordance with previous research findings. These findings provide insights for improving the performance of low-emissivity coatings in various applications.
