A process for synthesizing amorphous silica microspheres having fluorescence behavior includes the steps of placing into a container an organosilicon precursorand with a highly acidic solution and rinsing with a solvate to remove excess of the organosilicon precursor from the amorphous silica microspheres. The organosilicon precursor and the highly acidic solution are immiscible. The process for synthesizing amorphous silica microspheres also includes the steps adding a dopant from a group consisting of rhodamine-6G, rhodamine-B, europium 3+, fluorescein, coumarin-120, coumarin-314T, thionine, uranium and uranium-sensitized europium, stirring the organosilicon precursor and the highly acidic solution to form droplets of the organosilicon precursor in the highly acidic solution whereby water in the highly acidic solution hydrolizes the droplets of the organosilicon precursor to form amorphous silica microspheres and rinsing with a solvant to remove excess of the organosilicon precursor therefrom.
