Low-Temperature Synthesis and Structural Properties of PbMoO4 Nanocrystals

Low temperature synthesis and characterization of lanthanide-doped BaTiO3 nanocrystals.

The vapor diffusion sol-gel (VDSG) method was employed for the room-temperature synthesis of ~10 nm, aliovalently doped 0.4, 0.8, and 1.6 mol% La:BaTiO3 and 0.4, 0.6, and 1.2 mol% Dy:BaTiO3 nanocrystals. Maximum ensemble relative permittivities of 176 and 208 were observed in the 0.8 mol% La:BaTiO3 and the 1.2 mol% Dy:BaTiO3 nanocrystals, respectively, relative to 89 for undoped BaTiO3 (at 1 MH...

Synthesis, structural, and optical properties of stable ZnS:Cu,Cl nanocrystals.

Stable water-suspendable Cu+-doped ZnS nanocrystals (NCs) have been synthesized with mercaptopropionic acid (MPA) as a capping molecule. The nanocrystals have been characterized using a combination of experimental techniques including UV-vis and photoluminescence (PL) spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), inductively coupled plasma (ICP), and extended X-...

Low-temperature synthesis of LiFePO4 nanocrystals by solvothermal route

LiFePO4 nanocrystals were synthesized at a very low temperature of 170°C using carbon nanoparticles by a solvothermal process in a polyol medium, namely diethylene glycol without any heat treatment as a post procedure. The powder X-ray diffraction pattern of the LiFePO4 was indexed well to a pure orthorhombic system of olivine structure (space group: Pnma) with no undesirable impurities. The Li...

Low Temperature Hydrothermal Synthesis and Characterization and Optical Properties of Sr5Nb4O15 – Nb2O5 Nanocomposite

Sr5Nb4O15 – Nb2O5 nanocomposites were synthesized in 2 and 4 M KOH aqueous solutions, via a non-stoichiometric 1:2 Sr:Nb molar ratio hydrothermal method at 160°C for 48 h (S1 and S2, respectively). Sr(NO3)2 and Nb2O5 were used as raw materials. The synthesized nanomaterials were characterized by powder X-Ray diffraction (PXRD) technique. It was found that Sr5Nb4O15 has been crystallized in hexa...
