CuInS2 nanostructures were synthesized via a simple surfactant-free solvothermal route. In this synthesis, thiosemicarbazide and thioglycolic acid were used as sulfur sources. The effects of different parameters such as type of precursor and time on the morphology and particle size of the samples have been investigated. The nanostructures were characterized by means ...
A series of LaF3:Ce3+ phosphors for application in photodynamic therapy are synthesized using a one-stage solvothermal synthesis. The synthesis conditions; type and quantity stabilizer; concentration activator providing the maximum intensity UV- X-ray-excited luminescence; lowest size; highest colloidal stability phosphor nanoparticles found. As result this study, following parameters determine...
Bismuth selenide (Bi2Se3) nanostructures were synthesized via solvothermal method. The crystallinity of the as-synthesized sample has been analyzed by X-ray diffraction, which shows the formation of rhombohedral Bi2Se3. Electron microscopy examination indicates that the Bi2Se3 nanoparticles have hexagonal flake-like shape. The effect of the synthesis temperature on the morphology of the Bi2Se3 ...
We demonstrated that stepwise seed-mediated growth could be extended in non-aqueous solution (solvothermal synthesis) and improved as an effective method for controlling the uniform size of palladium nanoparticles (Pd NPs) in a wide range. The monodisperse Pd NPs with the size of about 5 nm were synthesized by simply reducing Pd(acac)2 with formaldehyde in different organic amine solvents. By a...
A method for the synthesis of 1,3-diarylpropylamines through hydroalkylation styrenes with benzylamines by potassium hydride has been developed. The protocol is initiated solvothermal treatment KH at 100 °C to generate deprotonated anionic species, which undergo selective C-alkylation arylalkenes 0 ambient temperature afford as major product.
Zinc oxide (ZnO) is a promising material which gained increasing interest in recent years owing to its preparation methods and remarkable performances. The paper presents the most common techniques for the synthesis of ZnO nanoparticles, such as mechanochemical process, precipitation, sol-gel method, solvothermal and hydrothermal processes. Due to their optical, mechanical, chemical and electri...
The title compound, (C(3)H(8)N(6))[AlF(5)(H(2)O)], was obtained by solvothermal synthesis from the reaction of aluminium hydroxide, 1,3,5-triazine-2,4,6-triamine (melamine), aqueous HF and water at 323 K for 48 h. The structure consists of [AlF(5)(H(2)O)](2-) octa-hedra and diprotonated melaminium cations. Cohesion is ensured by a three-dimensional network of hydrogen bonds.
