چکیده
Magnesium oxide (MgO) was synthesized by three different methods: the sol–gel (SG), microwave-assisted (MW), and hydrothermal (HT) methods for comparing influence of preparation conditions on properties products. The powders were annealed at 450 °C. samples characterized X-ray diffraction, scanning electron microscopy (SEM), transmission (TEM/HRTEM), selected area diffraction (SAED), energy-dispersive spectroscopy (EDX), BET specific surface porosity, photoluminescence, UV–Vis spectroscopy. consisted mainly periclase as a crystalline phase, MW HT generated particles with higher areas. had less-defined morphologies high levels aggregation. optical band gaps determined from UV DRS, photocatalytic activities magnesium oxides obtained towards degradation methyl orange (MO) under light irradiation evaluated.

ZnS : Cu phosphors were prepared by using laboratory grade chemicals through coprecipitating Cu along with ZnS using H2S and thiourea. Photo- and electroluminescence studies indicate that these phosphors have better emission characteristics compared to the phosphors in which activator is externally added. Phosphors with luminescence at ~530nrn were prepared. The difference between the character...
متن کاملA Comparative Study of Photocatalytic Activity of ZnO/activated Carbon Nanocomposites Prepared by Solid-state and Conventional Precipitation Methods
ZnO/activated carbon nanocomposites (ZnO/ACns) were synthesized by applying two different solid-state and precipitation methods. Precipitation method was initiated with zinc chloride and sodium hydroxide as starting materials in the presence of activated carbon. The synthesized sample was calcined at 250 °C for 1 h. The preparation of nanocomposite by solid-state method was accomplished by heat...

Systematic study of how different drying methods, namely hot-air drying, vacuum-drying, and freeze-drying, affect color, browning index, degree of rehydration, water solubility, and vitamin C content is critical for utilizing pine needle powders (PNP) as a novel ingredient in functional foods. Samples prepared by vacuum-drying showed a significantly higher L*-value, whereas higher a*- and b*-va...
متن کاملOptical Properties of Nanocrystal Interfaces in Compressed MgO Nanopowders
The optical properties and charge trapping phenomena observed on oxide nanocrystal ensembles can be strongly influenced by the presence of nanocrystal interfaces. MgO powders represent a convenient system to study these effects due to the well-defined shape and controllable size distributions of MgO nanocrystals. The spectroscopic properties of nanocrystal interfaces are investigated by monitor...
