“…[27][28][29] Griffini et al reported on the conversion and manipulation of light via luminescent down-shifting (LDS) by an elegant combination of lanthanide-doped polymer-derived ceramics incorporated with versatile nanopatterns for advanced optoelectronics, showing distinctively enhanced PCE and lifetime mainly attributed to the nanopattern assisted strong LDS property. 30 Chander et al reported a transparent LDS YVO 4 :Eu 3+ nano-phosphor layer to mitigate UV degradation in the TiO 2 -based perovskite solar cells, showing an improvement in stability under prolonged illumination and photocurrent due to LDS of incident UV photons into additional red photons.…”

This work investigates non-rare-earth phosphor (Sr4Al14O25:Mn4+, 0.5%Mg) with intensively red luminescence as a luminescent down-shifting layer for perovskite solar cells. The power conversion efficiency of the fabricated device with a structure of NiO/CH3NH3PbI3/[6,6]-phenyl C61-butyric acid methyl ester/Au coated with phosphor layer shows a 10% increase as compared with that of the control devices. Importantly, the phosphor layer coating can realize UV-protection as well as waterproof capability, achieving a reduced moisture-degradation of CH3NH3PbI3 perovskite upon applying an UV irradiation. Therefore, perovskite devices using this luminescent coating show a combined enhancement in both UV down-shifting conversion and long term stability. This can be expanded as a promising encapsulation technique in the perovskite solar cell community.

“…Here, the surface functionalization of commercial silica nanoparticles with octadecyltrichlorosilane was used to prepared SHNPs according to Siffalovic et al [5]. To monitore the antifungal effect, the EOs and EO/SHNP mixtures were used to treat sandstone, whitewood, and paper.…”

“…The super-hydrophobic nanoparticles (SHNPs) can self-assemble and form the superhydrophobic surfaces with hierarchical, micro-, and nano-scale roughness [1][2][3][4]. The superhydrophobic surface is defined as the one with a water contact angle larger than 150 • [5]. Air trapped in the roughness reduces the effective contact area on the liquid/solid interface and can give rise to very large contact angles of up to 177 • [1].…”

This study was undertaken to determine the in vitro antifungal activities of super-hydrophobic nanoparticles (SHNPs), essential oils (EOs), and their mixtures (SHNPs/EOs). We have applied a thin layer of SHNPs in combination with various concentrations of three EOs: Arborvitae (Thuja plicata), Oregano (Origanum vulgare L.), and Thyme (Thymus vulgaris). The mixtures were spread on the surface of different materials: whitewood, sandstone, and paper. The antifungal and protective properties of these SHNP and EO mixtures were evaluated. The parameter Rr (ratio of reflectivity) was determined to identify the color changes of substrates. Digital microscopy was used to measure the colonization area of molds and also their penetration in the analyzed materials. Surprisingly, the use of SHNPs alone showed a balanced compromise in order to inhibit the mold growth on assayed surfaces.

“…The development and advances in photonic gadgets are becoming more dependent on the availability of new functional materials, as these devices are gaining more importance in daily life in the form of sensors, light sources and energy harvesters [1][2][3][4][5] . An important characteristic of a material, that can be used in optical design, is its refractive index.…”

Polymer nanocomposites have gained much importance in the field of optoelectronics due to their unique optical properties. Refractive index engineering using nanoparticles is an effective strategy that could be applied for the fabrication of optical devices. Herein, we report three different strategies which are employed to enhance the refractive index of polymer thin films.These include incorporating cerium oxide nanoparticles onto the polystyrene matrix, secondly adding cerium oxide nanoparticles onto the cross-linkable polystyrene and thirdly by embedding functionalized cerium oxide nanoparticles onto the cross-linkable polystyrene. Refractive index of the polystyrene thin films was enhanced by dispersing neat CeO 2 nanoparticles and functionalized CeO 2 nanoparticles into the polystyrene matrix. 1.38 % enhancement in the refractive index of the polymer nanocomposite thin films could be achieved using our technique.The blending of polystyrene with cerium oxide nanoparticle presents a prospective way to engineer the refractive index of polymer thin films. We firmly believe that the study will be an effective guide towards future research in the area of surface engineering of polymer thin films for refractive index enhancement.
