摘要：Using semipermeable celloidin membrane as a basic template and organic reagents as cooperation additives, the CaCO3 crystals with different morphologies were successfully synthesized. All the products were characterized by transmission electron microscopy, X-ray powder diffraction, thermogravimetry, inductively coupled plasma atomic emission spectroscopy, etc. With the view of the different solubility products (Ksp) of La2(CO 3)3 and CaCO3, a novel core/shell CaCO3/La 2(CO3)3 composited fluorescent material was synthesized for the first time. The morphologies and properties of the core/shell CaCO 3/La2(CO3)3 composited fluorescent materials were also investigated. ? The Author(s) 2011.
