Uniform microcomposites of silica nanoparticles and lactose doped with Eu(III) have been successfully synthesized using a lab scale design of micro-fluidic-jet-spray-dryer (MFJSD). The dryer has a specially fabricated micro-fluidic-aerosol-nozzle (MFAN) to generate monodisperse droplets. Different Eu(III) loadings have been used to study the effects of precursor composition on particle drying. The morphologies and photoluminescence properties of the produced particles have been characterized by field emission scanning electron microscope, energy dispersive X-ray photoelectron spectrometer, and Fourier transform infrared spectra (FT-IR). Photoluminescence tests conducted on calcinated samples indicated higher intensity proportional to higher Eu(III) loading of the precursor solution. The FT-IR data confirmed that Eu(III) is likely to bond on the OH group of silica on the resulting composites.
