Sol–solvothermal synthesis and microwave evolution of La(OH)₃nanorods to La₂O₃nanorods

Abstract

Solvothermal synthesis of La(OH)3 sol and microwave radiation drying of La(OH)3 nanorods were employed for the first time to synthesize La2O3 nanorods with diameters around 10 nm and lengths up to 200 nm. The resulting products were characterized with XRD, TEM and HRTEM. Microwave radiation drying was found to be more effective to maintain the morphologies of nanorods than conventional drying.

Surface oxygen-vacancy induced photocatalytic activity of La(OH)3 nanorods prepared by a fast and scalable method

“…One-dimensional lanthanide hydroxides (La(OH) 3 ) have been of growing interest owing to their promising applications in sensors, 6 catalysts, 7,8 and capacitors. 9 Various synthesis techniques have been adopted for the preparation of La(OH) 3 nanostructures, including solvothermal, 10 hydrothermal, 11,12 precipitation, 13 and composite-hydroxide-mediated (CHM) methods. 6 However, these preparation methods generally need the use of surfactants/templates or complicated reaction conditions to get the desired shape/structure.…”

Synthesis of Monodisperse Lanthanum Hydroxide Nanoparticles and Nanorods by Sonochemical Method

“…Although many methods have been developed for the synthesis of lanthanum nanostructures including hydrothermal [25], solvothermal [26], micro emulsion or reverse micelles [27], sol gel [28], laser deposition [29] and other chemical and physical methods; some of these methods are affected by long reaction time, high temperature, high pressure, expensive surface materials (surfactant) and so on.…”

Upconversion nanoparticle as a theranostic agent for tumor imaging and therapy

“…Additionally, in a solvothermal system, the crystal growth can be controlled and products with di®erent morphologies can be gained. [31][32][33][34][35] Tian et al reported a modi¯ed liquid-solid solution solvothermal strategy for synthesizing Mn 2þ -doped NaYF 4 :Yb/Er nanoparticles, which possess the rational manipulation of red and green upconversion luminescence, and the pure dark red emission (650-670 nm). 36 …”
