A Novel Approach to Monodisperse, Luminescent Silica Spheres
Source abstract
Abstract
Monodisperse aminopropylsilica spheres were grown via a modified Stöber process with varying amounts of tetraethyl orthosilicate and (aminopropyl)triethoxysilane (APTES). Upon calcination, the spheres become luminescent, with the emission maximum dependent on the original APTES concentration. This provides a simple one-step route to gram-scale quantities of tailorable, luminescent, monodisperse silica spheres.

13. SEM experiments were performed on a field emission scanning emission electron microscope (Raith 150 with a Leo Gemini column). SEM images were typically acquired at 10 kV without gold sputtering. Average particle size and standard deviation was determined by imaging 20 random spheres. Confidence intervals were calculated at a 95% confidence level using atvalue of 2.093.
