“…However, it can be related to the previous study [22] presenting periodical regions of higher and lower content of SiO 2 in the mixture coating deposited as a layer of constant refractive index. This periodicity has been related to the rotation of the sample placed at calotte and lateral positions of evaporation material crucibles indicating that the mixture of materials in the vapour is not uniform in the chamber.…”

Gradient index coatings and optical filters are a challenge for fabrication. In a round-robin experiment, basically the same hybrid antireflection coating for the visible spectral region, combining homogeneous refractive index layers of pure materials and linear gradient refractive index layers of material mixtures, has been deposited. The experiment involved three different deposition techniques: electron-beam evaporation, ion-beam sputtering, and radio frequency magnetron sputtering. The material combinations used by these techniques were Nb 2 O 5 ͞SiO 2 , TiO 2 ͞SiO 2 , and Ta 2 O 5 ͞SiO 2 , respectively. The spectral performances of samples coated on one side and on both sides have been compared to the corresponding theoretical spectra of the designed profile. Also, the reproducibility of results for each process is verified. Finally, it is shown that ion-beam sputtering gave the best results in terms of deviation from the theoretical performance and reproducibility.

“…Recently, refractive index‐matched structures have been found to minimize Fresnel reflection loss, so that light is transmitted through a touch screen more efficiently . However, limited research has been conducted on variations in the optical properties due to the addition of index‐matching layers (IMLs) with different refractive indices on OMO tri‐layer structures …”

For the commercial application of transparent conductive oxide (TCO) materials in touch screens, the incident light should be reflected at the interfaces between the stacked TCO layers having different refractive indices. To reduce optical loss, the presence of an index-matching (IM) passivation layer between the conductive layer and substrate is necessary. The objective of the present study is to evaluate and compare the effects of an IM layer (SiO 2 /TiO 2 ) on the optical spectra and color variation in the case of MTO/ Ag/MTO films with and without the SiO 2 /TiO 2 layers. The optical properties are systematically investigated using an ultraviolet (UV)-visible (Vis) spectrophotometer. The optical transmittance of all fabricated films is higher than 85% at the wavelength of 550 nm. The optimal thickness of the SiO 2 /TiO 2 layer is SiO 2 (90, 100 nm)/TiO 2 (10 nm). A low reflectance difference (ΔR 550nm ) of 1.5 and 1.3%, and the color difference representing the blueyellow color (Δb Ã ) of 0.6 and 3.1 are achieved with the optimal thickness of SiO 2 (90 and 100 nm)/TiO 2 (10 nm), respectively.
