A facile template synthesis has been developed to obtain monodisperse spherical mesoporous nanocomposite mSiO 2 /C-dots/Eu 3+ particles of submicron size exhibiting bright broadband luminescence in the visible spectral range. The use of europium ions made it possible to increase the integrated emission intensity of the nanocomposite particles in the reddish-orange region. The particles have a specific surface area of 540 m 2 /g, pore volume of 0.35 cm 3 /g, and average pore diameter of 2.7 nm. The obtained particles are promising for application in nanomedicine as nanocontainers simultaneously serving as biomarkers.
