Nano-crystals of ZnO, Eu 3+ doped and Li + , co-doped ZnO have been prepared by urea hydrolysis in ethylene glycol medium at 150 °C. Ethylene acts as capping agent for nanoparticles. Three colors 437 (blue), 540 (green) 615 nm (red) from 2 at.% 5 observed luminescence studies compared to that at.%. which shows emission nm. It is established green light originated the oxygen vacancy brought incorporation into ZnO. Particles are re-dispersible organic solvent such ethanol, able incorporate...

The antimicrobial effects of copper ions and salts are well known, but the cuprous oxide nanoparticles (Cu2O-NPs) on staphylococcal biofilms have not yet been clearly revealed. present study evaluated Cu2O-NPs for their antibacterial antibiofilm activities against heterogeneous vancomycin-intermediate Staphylococcus aureus (hVISA) S. (VISA). Nanoscaled Cu2O, generated by solution phase technology, contained Cu2O octahedral nanoparticles. Field emission electron microscopy demonstrated...

Nanocrystalline semiconductors exhibit different properties due to two basic factors. They possess high surface volume ratio and the actual size of particle can determine electronic physical material. The small results in an observable quantum confinement effect, defined by increasing bandgap accompanied quantization energy levels discrete values. In present work we have synthesized series cadmium selenide/cadmium telluride (CdSe/CdTe) core/shell CdSe/CdTe/CdS core/shell/shell investigate...

Liquid – liquid interface reaction is the method forpreparation nanoparticles (NP'S) which depend on supersaturation of ions that provide by using system consist fromtoluene and water, first one above second to obtainnanoparticles (NP's) CdS at separated between thesetwo immiscible liquid. The structure properties were characterized byXRD-diffraction transmission electron microscopy.The crystalline size estimate from X-ray diffraction patternusing Scherer equation be about 7nm,and TEM...
