Microwave-Hydrothermal Synthesis and Characterization of High-Purity Nb Doped BaTiO3 Nanocrystals
The synthesis of Nb doped BaTiO3 has been investigated under Microwave-Hydrothermal (MH) conditions in the temperature of 150°C for only 2 h using C16H36O4Ti, BaH2O2.8H2O and NbCl5 as Ba, Ti and Nb sources, respectively. Typical experiments performed on MH processing have not yet reported for Nb doped BaTi...
متن کاملConvectional hydrothermal synthesis of high-purity pesudo-cubic BaTi0.09Nb0.01O3 nanocrystals in rotary autoclave
Nano-sized BaTiO3 powders with particular Nb concentrations were prepared by Rotary- Hydrothermal (RH) method. Hydrothermal method was used at 180 °C for 5 hours with new Ti pressure and the teflon vessel was rotated at a speed of 160 rpm during the hydrothermal reaction. New hydrothermal method was used instead of previous solid state reaction for the system BaTiO3±Nb<sub...

متن کاملColloidal synthesis of germanium nanocrystals
In this study, colloidal germanium nanocrystals were synthesized by a simple and novel method, and their optical properties were also studied. Polyvinyl alcohol (PVA) as a surface modifier was used to control the optical properties of colloidal Ge nanocrystals. Fourier transform infrared spectroscopy (FTIR) analysis was performed to identify the various functional groups present in the sample. ...
متن کاملBi-functional NaLuF4:Gd3+/Yb3+/Er3+ nanocrystals: hydrothermal synthesis, optical and magnetic properties
Magnetic-fluorescent lanthanide doped sodium lutetium fluoride (NaLuF4:Yb3+/Er3+/Gd3+) nanocrystals were synthesized via facile hydrothermal method by varying concentration of Gd3+. Powder X-ray powder diffraction (PXRD), scanning electron microscopy (SEM),transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), p...
