Indium tin oxide (ITO) is the most widely used transparent conductor in applications such as light emitting diodes, liquid crystal devices, touch screens, and photovoltaic cells. So far, its use has mainly been limited to visible range (380 nm–750 nm), it reflects at longer wavelengths and, consequently, transmission low. Here, we introduce a simple technique, based on high temperature annealing, which can reduce reflection near-infrared (750 nm–2400 nm). With an optimized set of parameters,...
Abstract Metallic copper is a potent antimicrobial agent with high efficacy against range of microorganisms. Whilst it commonplace for objects such as door handles and hospital bedrails to be made or coated copper, other high-touch surfaces those screens monitors would lose their optical transparency. Herein, we report the design transparent nanostructured surface obtained by dewetting ultrathin metal films on glass. Antimicrobial effectiveness >99.9 % was within 2 h Staphylococcus aureus...
Abstract Colloidal semiconductor quantum dots (QDs) can be considered a promising material platform for solution‐processed laser diodes. However, due to some fundamental challenges, the realization of electrically pumped lasing based on QDs remains unresolved. Here, binary blend and ZnO nanocrystals is employed, which serve as nano‐sized scatterers facilitate waveguide gain in ultra‐thin films. By carefully engineering electric field these films, an infrared amplified spontaneous emission...
Abstract Ultrathin materials often require high temperatures for growth and processing, which cannot be withstood by the substrate underneath. For example, polymers are widely used as a supporting layer but unfortunately have low strain-point temperatures. This is case of polyethylene terephthalate (PET) has glass transition melting 76 250 °C, respectively. In this paper we propose to use polished salt, material that can withstand during fabrication and, at same time, sacrificed transfer...
Abstract Engineering the doping level in graphene is essential to realizing functional electronic and optoelectronic devices. While achieving strong p-doping relatively straightforward, electrostatic or chemical approaches negatively dope have yielded electron densities ( n s ) of −9.5 × 10 12 cm −2 below. In this work, we demonstrate very high (−10 13 −10 14 graphene, on an ion-exchanged glass substrate, which widely used touch screen displays (e.g. smart phones). Moreover, proposed method,...
