摘要
In this communication, a hydrothermal method for synthesizing cadmium sulfoselenide inclusion pigment was introduced. The general synthesis procedure was as follows: (1) the hydrothermal preparation of CdS (x) Se(1-x)-CeO2 nanoparticles; (2) the dispersion of the CdS (x) Se(1-x)-CeO2 nanoparticles in a prehydrolyzed TEOS; (3) the formation of a CdS (x) Se(1-x)-CeO2-SiO2 nano-composite by the gelation of the prehydrolyzed TEOS; (4) the inclusion of the CdS (x) Se(1-x) into the SiO2-CeO2 matrices by a hydrothermal treatment. The crystalline phase, thermal effect, microstructure and L*a*b* color parameters of the pigment were investigated by X-ray diffraction (XRD), a Differential Scanning Calorimeter (DSC-TG), a transmission electron microscope (TEM) and a differential colorimeter. The results showed that CdS (x) Se(1-x) could be partially stabilized to more than 1100 degrees C by the hydrothermally-densified CeO2-SiO2 glassy phase. The inclusion pigment showed a stable red color at 1100 degrees C, though it was not bright red.
