Cubic and spindle-shaped CaCO 3 particles were successfully prepared using carbonation method without any additional crystal controlling agent. The experimental results showed that carbonation temperature and initial concentration of Ca(OH) 2 slurry are the main factors to influence the morphology of CaCO 3 particles. The as-prepared cubic and spindle-shaped CaCO 3 ...
Uniform TiO 2 :Eu 3+ nanorods and spindle-shaped nanoparticles have been successfully prepared through simple calcination and two-step hydrothermal processes using titanate as the precursor. X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectrophotometer, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and photoluminescence spectra (PL) were...
