Spherical SiO2/CaMoO4∶Eu3+,Li+ Red Phosphor Synthsized via Homogeneous Precipitation and Combustion Method and Its Luminescence Properties
摘要
Abstract
The spherical core-shell structured SiO2/CaMoO4:Eu3+,Li+ phosphors were prepared by a combined approach of homogeneous precipitation and combustion synthesis. The structure, morphology and luminescence properties of the SiO2/CaMoO4:Eu3+,Li+ phosphors were characterized by powder X-ray diffraction, scanning electron microscopy, transmission electron microscopy and pho-toluminescence, respectively. The results show that the products are composed of tetragonal phase CaMoO4 and amorphous SiO2, the CaMoO4:Eu3+,Li+ particles are well-crystallized on the SiO2 spheres, and the obtained microspheres with the uniform size distribution have a core-shell structure. The SiO2/CaMoO4:Eu3+ microspheres exhibited an intensive red emission of 617 nm under near ultraviolet (395 nm) excitation.关键词
