Fluorescence, morphology, and colloidal stability of the particles have been studied using spectrofluorimetry, z -potential, and scanning electron microscopy respectively. Sphericity and colloidal stability are characterized for different concentrations of BAlq for each layer. The molecule adsorption capacity of BAlq on silica has been investigated to understand the adsorption mechanism. This approach opens an avenue for the incorporation of non-polar dyes into silica nanoparticles while maintaining the sphericity and colloidal stability of pure silica nanoparticles.
