We have studied the luminescence of planar nanostructures based on amorphous copper, excited by a low-intensity source in the UV region of the spectrum. We have shown that it is dependent on the packing density of copper granules on the surface of the quartz substrate, the presence of chains of granules, the optical properties of the surrounding medium, and the oxidation time. The observed maxima at the wavelengths of 400 nm and 520 nm correspond to luminescence of the quartz and copper oxide Cu2O. The maximum at 650 nm is located in the region of plasma resonances of the oxidized copper chains and aggregates, and is enhanced in the “hot spot” region near the surface of interacting copper particles.
