Photoactive Cu-doped ZnO–ZnAl2O4 ceramic nanocomposites and coatings were prepared by polymer-salt method. The luminescent spectroscopy, scanning electron microscopy (SEM) X-ray diffraction methods used for the study structure, morphology materials properties. consist of small hexagonal ZnO cubic ZnAl2O4 nanocrystals having size about 10 nm. luminescence properties shows that can be as light do...

The development of sensor materials which gas sensitivity activates under light illumination is great importance for the design portable analyzers with low power consumption. In present work a ZnO/CsPbBr3 nanocomposite based on nanocrystalline ZnO and colloidal cubic-shaped perovskite CsPbBr3 nanocrystals (NCs) capped by oleic acide oleylamine was synthesized. individual obtained are characteri...

Native coordinating ligands acquired during the chemical synthesis of colloidal nanocrystals are optimized primarily for their ability to exert control over nanocrystal size, composition, morphology, and dispersibility, and not necessarily for their final application. In general, they are hydrophobic and highly insulating, and constitute a significant barrier for charge or ion transport in devi...

We report a new integration approach to produce arrays of ZnO microcrystals for optoelectronic and photovoltaic applications. Demonstrated applications are n-ZnO/p-GaN heterojunction LEDs and photovoltaic cells. The integration process uses an oxygen plasma treatment in combination with a photoresist pattern on Magnesium doped GaN substrates to define a narrow sub-100nm width nucleation region....
