In Situ Observation of Epitaxial Growth during Evaporative Simultaneous Crystallization from Aqueous Electrolytes in Droplets

چکیده
In this study, crystallization phenomena were investigated by real-time in situ observation of seeded droplets under evaporation using a self-developed hot-stage platform. Ternary solutions at eutonic conditions 25 °C for the following systems: NaCl–KCl–H2O, NaCl–CaSO4–H2O, and NaCl–Na2SO4–H2O. Evidence epitaxial growth was found aqueous NaCl–KCl NaCl–Na2SO4. Sodium chloride nucleated grew epitaxially upon other substrates larger proportion compared with inverse. This could be related to higher solubility, consequently residual supersaturation NaCl regarding components. Hopper-like crystals developed almost all systems. The results may help devise strategies control particle morphologies purity industrial from complex

15 صفحه اولIn situ observation of antisite defect formation during crystal growth.
In situ x-ray diffraction (XRD) coupled with molecular dynamics (MD) simulations have been used to quantify antisite defect trapping during crystallization. Rietveld refinement of the XRD data revealed a marked lattice distortion which involves an a axis expansion and a c axis contraction of the stable C11b phase. The observed lattice response is proportional in magnitude to the growth rate, su...
متن کاملAnalysis of the Efficient High-Temperature In Situ Photoluminescence from GaN Layers during Epitaxial Growth
Photoluminescence (PL) in GaN or InGaN layers monitored during epitaxial growth at high temperatures permits a quasi-continuous in situ characterization of opto-electronic properties. Therefore, epitaxial parameters can now be optimized at the earliest possible stage. A pulsed and high-power UV laser was required for PL excitation at high temperatures. Herein, the underlying nonlinear mechanism...
