Facile control of silica nanoparticles using a novel solvent varying method for the fabrication of artificial opal photonic crystals
{{output}}
In this work, the Stöber process was applied to produce uniform silica nanoparticles (SNPs) in the meso-scale size range. The novel aspect of this work was to control the produced silica particle size by only varying the volume of the solvent ethanol used, wh... ...
