چکیده
Germanium dioxide has many applications in the optoelectronics sector and is the subject of substantial research interest. In this contribution we report the preparation of germanium dioxide nanoparticles (NPs) of varied sizes and morphologies using a facile sol-gel methodology that requires no addition of templating agents (e.g., surfactants). Morphological control is achieved by tailoring the reaction mixture water/ethanol ratio, ammonium hydroxide concentration, time, and temperature.

Shape-controlled synthesis of Prussian blue analogue Co3[Co(CN)6]2 nanocrystals.
Prussian blue analogue Co3[Co(CN)6]2 nanostructures with morphologies of truncated nanocubes (polyhedra), cubes and rods, were synthesized in large quantities by a direct dissociation of the single-source precursor K3[Co(CN)6] in a microemulsion system; the molar ratio of H2O to surfactant and the concentration of K3[Co(CN)6] both played important roles in determining the shape of the product.
متن کاملSurfactant-controlled composition and crystal structure of manganese(II) sulfide nanocrystals prepared by solvothermal synthesis
We investigated how the outcome of the solvothermal synthesis of manganese(II) sulfide (MnS) nanocrystals (NCs) is affected by the type and amount of long chain surfactant present in the reaction mixture. Prompted by a previous observation that a larger than stoichiometric amount of sulfur is required [Puglisi, A.; Mondini, S.; Cenedese, S.; Ferretti, A. M.; Santo, N.; Ponti A. Chem. Mater. 201...
متن کاملChemical synthesis of the Co3O4 nanoparticles in presence of CTAB surfactant
Sphere-like shaped cobalt oxide nanoparticles (Co3O4) were synthesized by a simple wet chemical method using cobalt chloride as precursor and cetyl trimethylammonium bromide (CTAB) as surfactant. Their structural and surface morphologial properties were characterized by high resolution transmission electron microscopy (HRTEM), field emission scanning electron microscopy (FESEM) and X-ray diffra...
متن کاملNaGd(MoO4)2 nanocrystals with diverse morphologies: controlled synthesis, growth mechanism, photoluminescence and thermometric properties
Pure tetragonal phase, uniform and well-crystallized sodium gadolinium molybdate (NaGd(MoO4)2) nanocrystals with diverse morphologies, e.g. nanocylinders, nanocubes and square nanoplates have been selectively synthesized via oleic acid-mediated hydrothermal method. The phase, structure, morphology and composition of the as-synthesized products are studied. Contents of both sodium molybdate and ...
