Synthesis and characterization of wire-like and near-spherical Eu2O3-doped Y2O3 phosphors by solvothermal reaction

Effect of solvents on morphology and photocatalytic activity of BiOBr synthesized by solvothermal method

“…The various morphologies of BiOBr crystals obtained in the different solvents can be expressed by considering some properties of the solvents (Table 1) [12], whose formation mechanisms are proposed (Scheme 1) based on the above observation. In ethanol, the low viscosity, low dielectric constant and thermal conductivity lead to the high diffusion rate of ions and high supersaturation in the solution.…”

Structural and optical properties of europium doped yttrium oxide nanoparticles for phosphor applications

“…The enhancement of luminescence efficiency due to well crystallinity, high phase purity and calcinations temperature of the europium doped yttrium oxide nanoparticles is reported recently [26,27]. In solvothermal synthesis, the solvent effect on the morphology of the europium doped yttria nanoparticles is studied by Yin et al [28]. In the above-mentioned methods, it is very difficult to maintain homogeneity of the product and control the particle size simultaneously.…”

Effect of propylene glycol-water ratio on morphology of Y2O2S particles prepared by complex homogeneous precipitation method

“…As a result, nucleation starts to dominate particles growth, and smaller particles with regular morphology can be obtained. Such an effect was observed by Yin with co-authors 15) in the solvothermal preparation of Y 2 O 3 using ethanol, ethylene glycol or glycerol water solutions. The increase of the solution viscosity due to the nature of the organic component resulted in the decrease of particles size.…”
