(Zn,Mn)S nanoparticles with Mn concentrations ranging from 1% to 30% and in a wire‐like arrangement were formed inside mesoporous SiO 2 matrices of various pore diameters. The nanoparticles were characterised using photoluminescence and excitation spectroscopy. It is found, that the Mn 2+ ions are incorporated on cation lattice sites replacing Zn. The decay times of the internal Mn 2+ (3d 5 ) luminescence are studied in detail by time resolved spectroscopy over more than 5 orders of magnitude in intensity. A concentration and a remarkable size dependence of the time behaviour has been observed indicating a geometry dependence of the energy transfer processes within the Mn system.
