“…The band gap of the CuI films varies in the range of 2.71–3.14 eV for the deposition time of 5–10 min. These results are consistent with previous reports [43,48–49] . However, this change in band gap may be engineered for solving the problem of valance band offset in CuI/n−Si solar cell that would enhance the performance of the solar cells [50–51] .…”

Copper iodide (CuI) thin films were prepared on a glass substrate by a facile high pressure (HP)‐PECVD method at room temperature. For this, CuI powder was dissolved in CH3CN. The CuI vapor with plasma was investigated by Optical Emission Spectroscopic (OES) data for identifying the species in the plasma. The XRD study reveals the polycrystalline nature of the films. The SEM analyses indicate the homogeneity of the films. The EDS mapping confirms that the thin films mostly consisted of carbon followed by nitrogen, copper and iodine, respectively. The band gaps of CuI thin films were in the range of ~2.71–3.14 eV. The high transmittance and band gap engineering in HP‐PECVD‐synthesized CuI thin films indicates their potential use as window and hole transport layers in low cost solar cells.

“…Deposition of copper iodide films via SILAR was carried out at room temperature in accordance with [15] using an aqueous solution containing 0.1 M CuSO4 and 0.1 M Na2S2O3 as the cationic precursor, where a copper (I) thiosulfate complex Na[Cu(S2O3)] was formed, from which Cu + ions were released into solution. The PET substrates were immersed into the cationic precursor for 20 s. Then, the substrates were washed in distilled water for 10 s. For the reaction of the strongly adsorbed Cu + ions on the PET surface with I − ions to obtain some CuI monolayers, the substrate was then immersed for 20 s into aqueous NaI solution (anionic precursor), whose concentration was 0.05, 0.075 or 0.1 M. After that, the PET substrate with the thinnest CuI film was washed in distilled water for 10 s. The listed procedure was one SILAR cycle of CuI film deposition.…”

“…As UV protective canopies and other UV shields should have large areas, a preference must be given to affordable and mass-production deposition methods. Among such methods, Successive Ionic Layer Adsorption and Reaction (SILAR) technique allows deposition of the nanostructured doped and undoped ZnO [14] and CuI [11,15] thin films over large areas and suggests low capital expenditure based on simple process equipment.…”

In this work, we study a suitability for protection against terrestrial ultraviolet part of the solar spectrum of undoped and doped by indium zinc oxide thin nanostructured films, ZnO and ZnO:In, respectively, and cuprous iodide (CuI) films obtained via Successive Ionic Layer Adsorption and Reaction (SILAR) techniques on the lightweight low cost poly(ethylene terephthalate) (PET) flexible substrates. The film morphology is observed by scanning electron microscopy (SEM). Chemical compositions of the films are investigated by X-ray fluorescence (XRF) microanalysis. To research crystal structure we used X-ray diffraction (XRD) method. The UV-protection ability of the nanostructured thin films, PET tapes and samples consisting of the PET substrates and the films deposited on them by the SILAR method has been evaluated on the base of their optical properties in accordance with an international standard ISO 2443:2012(E) "Determination of sunscreen UVA photoprotection in vitro". According to the research, nanostructured ZnO, ZnO:In and CuI thin films made by the cheap, affordable, and suitable for mass production SILAR method on thin flexible cheap PET substrates have been proposed as a new material for UV-shielding applications. In accordance with an international standard ISO 2443:2012(E), UV-protection ability of the samples consisting of the PET substrates and the films deposited on them by the SILAR method fits the category "excellent" (50+). The best low cost flexible and lightweight UV shielding material turned out to be that consisted from ZnO:In film and PET substrate, the sun protection factor of which equals 157.

The paper presents the fabrication and characterization of [CuI(L)]n thin films, where L represents various alkylpyridine ligands including 4-methylpyridine, 3-methylpyridine, 2-methylpyridine, 4-tbutylpyridine, 3,4-dimethylpyridine, and 3,5-dimethylpyridine. The thin films were synthesized by exposing the corresponding ligands to CuI thin films through vapor deposition. The coordination reactions occurring on the films were investigated using PXRD and time-dependent photoluminescence spectroscopy, and a comparison was made between the structures of the thin films and the corresponding powder phases. The films showed primarly blue emission (λem = 457–515 nm) and polymeric structures with excited state lifetimes ranging from 0.6 to 5.5 μs. Significantly, the studied compounds exhibited fast reversible luminescence quenching when exposed to vapors of dichloromethane and dibromomethane (15 and 30 min respectively), and the luminescence was restored upon re-exposure to the alkylpyridine ligand (after 20 min). These findings indicate that these thin films hold promise for applications as sensors (with sensitive and reversible detection capability) for volatile halogen-based compounds (VHC).
