Nickel oxide (NiO) is a wide band gap semiconductor material that used as an electrochromic layer or ion storage in devices. In this work, the effect of annealing temperature on sol-gel NiO films was investigated. Fourier transform infrared spectroscopy (FTIR) showed formation via decomposition precursor nickel acetate occurred at about 300 °C. Meanwhile, increase roughness observed by Atomic force microscope (AFM), and precipitation large number crystallites 500 X-ray Diffraction (XRD) film...
As consumers pursue higher display quality, Mini-LED backlight technology has become the focus of research in current field. With its size advantage (100–200 μm), it can achieve one-thousand-level divisional dimming, and also be combined with quantum dot to greatly improve contrast, color gamut, dark state other element performance LCD displays. is undoubtedly most ideal solution realize a highly dynamic range displays, been widely commercialized many fields such as TVs, tablet computers,...

This paper focuses on key technologies involved such chip mass transfer, full-color display, bonding driving research history frontier progress these reviewed detail. For epitaxy...
The concept of “high entropy” was first proposed while exploring the unknown center metal alloy phase diagram, and then expanded to oxides. colossal dielectric constant found on bulk high-entropy oxides (HEOs) reveals potential application in aspects. Despite fact that known HEO thin films have not been reported field properties so far, with effects theoretical guidance high entropy, it is predictable they will be discovered. Currently, researchers are verifying appropriately increasing...
Efficient white-light-emitting diodes (WPLEDs) based on a polymer codoped with two phosphorescent dyes were fabricated by the spin-casting method. Polyhedral oligomeric silsesquioxane-terminated poly(9,9-dioctylfluorene) (PFO-poss) was used as host and blue light emitter. Phosphorescent emitters, fac-tris[2-(4′-ter-butyl)phenylpyridine] iridium (III) [Ir(Bu-ppy)3] bis-(1-phenylisoquinolyl)iridium(III)(1-trifluoro) acetylacetonate [(Piq)2Ir(acaF)] green red emission, respectively, guests.

Abstract Shrinking the device dimension has long been pursuit of semiconductor industry to increase density and operation speed. In application thin film transistors (TFTs), all-organic TFT arrays made by all-solution process are desired for low cost flexible electronics. One greatest challenges is how achieve ultrashort channel through a cost-effective method. our study, ultrashort-channel devices demonstrated direct inkjet printing conducting polymer as source/drain gate electrodes without...
Tungsten oxide (WO3) electrochromic devices have attracted a lot of interest in the energy conservation field and shown preliminary application potential market. However, it is difficult to quantitatively direct experiments with existing theoretical models, which can restrict further development electrochromism. Here, an physical simulation model WO3 films was built solve above problem. Experimentally, actual kinetics LiClO4/propylene carbonate electrolyte determined as continuous...
The treatment of wastewater using microalgae is regarded as a green and potential technology.

Abstract Summary: A strategy to generate an efficient white‐light emission has been developed by mixing fluorescence and phosphorescence from a single polymer. Fluorene is used as the blue‐emissive component, benzothiadiazole (BT) iridium complex [(btp) 2 Ir(tmd)] are incorporated into polyfluorene backbone, respectively, green‐ red‐emissive chromophores Suzuki polycondensation. By changing contents of BT in polymer, electroluminescence spectrum polymer can be adjusted achieve emission....
The electron mobility of 4,7-diphyenyl-1,10-phenanthroline (BPhen) at various thicknesses (50–300nm) has been estimated by using space-charge-limited current measurements. measured bulk is in excellent agreement with results from time-of-flight method. It observed that the BPhen approaches its true value when thickness more than 150nm. 300nm found to be 3.4×10−4cm2∕Vs (at 0.3MV∕cm) weak dependence on electric field. For typical organic light-emitting devices, also investigated. At request...
The influence of excitation wavelength and embedding media on fluorescence blinking statistics 4 nm × 20 cadmium selenide (CdSe) nanorods is investigated.
