摘要： Micron-scale hollow spheres were successfully constructed with silica nanoparticles by templating of polymer spheres. Subsequently, the use of 3-aminopropyltriethoxysilane (APTES) introduces carbon and oxygen defects in the silica nanoparticles resulting from calcination of the aminopropyl group. In this approach, the template of micron-scale polymer spheres was prepared from dispersion polymerization. Subsequent Stöber process results in the formation of a silica layer attached to the polymer sphere surfaces. After calcination, the obtained micron-scale hollow silica spheres were then studied on the relationship between the particle diameter and the surface morphology. The luminescence of hollow spheres was prepared through using APTES in Stöber process, and which of related the appearance of luminescence to the APTES concentration and calcination temperature. The results of this study can provide useful information for the structure of micron-scale hollow spheres and their application to luminescent materials. 其他題名： Colloid Polym Sci 出版者： Berlin/Heidelberg: Springer-Verlag 出版日期： 2012-11-01 出處： Colloid and polymer science, 2012-11, Vol.290 (17), p.1777-1784 版權： Springer-Verlag 2012 版權： 2015 INIST-CNRS 版權： Colloid and Polymer Science is a copyright of Springer, 2012. 識別號： ISSN: 0303-402X 識別號： EISSN: 1435-1536 識別號： DOI: 10.1007/s00396-012-2716-9 識別號： CODEN: CPMSB6
