Fabrication of light-emitting porous hydromagnesite with rosette-like architecture

2003 
Porous hydromagnesite with rosette-like morphologies has been synthesized at 100 °C by a convenient hydrothermal method with the absence of additives or organic surfactants. The hydromagnesite particles are spherical with a diameter of about 250 μm. The thermal behavior of the product has been investigated by TGA-DTA technique, whilst the decomposition mechanism was confirmed by in situ high temperature X-ray diffraction analysis. The as-prepared hydromagnesite was found to have a photoluminescent emission at about 448 nm.
