in this pepper fe2o3 nanoparticles were synthesized via a fast microwave method. then fe2o3-tio2 nanocomposites were synthesized by a sonochemical-assisted method. the prepared products were characterized by x-ray diffraction pattern, scanning electron microscopy and fourier transform infrared spectroscopy. the photocatalytic behaviour of fe2o3-tio2 nanocomposites was evaluated using the degrad...

The defect tolerance of halide perovskite materials has led to efficient optoelectronic devices based on thin-film geometries with unprecedented speed. Moreover, it has motivated research on perovskite nanowires because surface recombination continues to be a major obstacle in realizing efficient nanowire devices. Recently, ordered vertical arrays of perovskite nanowires have been realized, whi...

The successful development of ferroelectric polymer devices depends on the effective fabrication of polar ferroelectric crystalline nanostructures. We demonstrate, by scanning X-ray microdiffraction using synchrotron light, the heterogeneous character of high aspect ratio one-dimensional nanoarrays of poly(vinylidene fluoride-co-trifluoroethylene) copolymers supported by a residual polymer film...

Extending plasmonics into the ultraviolet range imposes use of aluminum to achieve best optical performance. However, water corrosion is a major limiting issue for UV plasmonics, as this phenomenon occurs significantly faster in presence light, even at low laser powers few microwatts. Here we assess performance nanometer-thick layers various metal oxides deposited by atomic layer deposition (AL...

The continuous performance optimization of tris(8-hydroxyquinoline)aluminum (Alq3) materials is great significance during the commercialization process organic light-emitting diodes (OLEDs). In incorporating Ag nanostructures into Alq3, photophysical properties are greatly improved by plasmon–exciton coupling effect. Localized surface plasmons (LSPs) in nanoparticles (NPs) efficiently increased...

Tubular nanostructures have stimulated extensive research efforts in recent years because of their technological importance in advanced electronic or magnetic devices and prospective applications in catalysis, sensors, and biological separation and transport. To date, various methods including reductive sulfidization, thermal decomposition of precursors, atomic layer deposition (ALD), hydrother...

Nanotubes are fabricated by atomic layer deposition (ALD) into nanopore arrays created by anodic aluminum oxide (AAO). A transmission electron microscopy (TEM) methodology is developed and applied to quantify the ALD conformality in the nanopores (thickness as a function of depth), and the results are compared to existing models for ALD conformality. ALD HfO2 nanotubes formed in AAO templates a...

Phosphor-free apple-white light emitting diodes have been fabricated using a dual stacked InGaN/GaN multiple quantum wells comprising of a lower set of long wavelength emitting indium-rich nanostructures incorporated in multiple quantum wells with an upper set of cyan-green emitting multiple quantum wells. The light-emitting diodes were grown on nano-epitaxially lateral overgrown GaN template f...

Hybrid nanostructured arrays based on carbon nanotubes (CNT) and palladium or titanium dioxide materials have been synthesized using self-supported and silicon-supported anodized aluminum oxide (AAO) as nanoporous template. It is well demonstrated that carbon nanotubes can be grown using these membranes and hydrocarbon precursors that decompose at temperatures closer to 600°C without the use of...
