Arrays of CdS:Mn2+:Cu+ micro‐ and nanowires grown in polycarbonate ion‐track templates exhibit photoluminescence in the spectral domain ranging from 500 to 800 nm at room temperature. A comparison with similar CdS and CdS:Mn2+ wire arrays is presented. The individual contributions to the emission spectra of Cu+ and Mn2+ ions in the CdS matrix are explained using their energy level schemes. Also SEM, EDX and EPR data are given for these wires.
