Microwave–Assisted Hydrothermal Synthesis and Optical Characterization of SnO2 Nanoparticles
Semiconductor nanoparticles exhibit size dependent properties due to quantum confinement effect that are not present in their bulk counterparts. In this work, extremely fine and pure SnO2 nanoparticles of ~1.1 nm size were synthesized by a solution process, in which amorphous precipitate of SnO2 was crystallized by microwave heating. The particles sizes varied from ~1.1 to ~2.7 nm. By XRD analy...
متن کاملFacile controlled synthesis and growth mechanisms of flower-like and tubular MnO2 nanostructures by microwave-assisted hydrothermal method.
Birnessite flower-like and α-type tubular MnO(2) nanostructures were selectively synthesized through simple decomposition of KMnO(4) under hydrochloric acid condition by controlling reaction temperature using a microwave-assisted hydrothermal method. The as-prepared samples were characterized in detail by various techniques including X-ray diffraction, field emission scanning electron microscop...
متن کاملControlled Hydrothermal Synthesis and Photoluminescence of Nanocrystalline ZnGa2O4:Cr3+ Monospheres
The hydrothermal synthesis of nanocrystalline ZnGa2O4:Cr3+ (ZGC) red phosphor monospheres was accomplished in this work, and the effects of system pH, reactant content, reaction time, and citrate anions (Cit3-) on the phase and morphology evolution of the product were systematically studied. Under the optimized conditions of Cit3-/M = 1.0 molar ratio (M = total cations), pH = 5.0, and 0.2 mmol ...

متن کاملMicrowave Synthesis, Characterization, and Photoluminescence Properties of Nanocrystalline Zirconia
We report synthesis of ZrO₂ nanoparticles (NPs) using microwave assisted chemical method at 80°C temperature. Synthesized ZrO₂ NPs were calcinated at 400°C under air atmosphere and characterized using FTIR, XRD, SEM, TEM, BET, and EDS for their formation, structure, morphology, size, and elemental composition. XRD results revealed the formation of mixed phase monoclinic and tetragonal ZrO₂ phas...
