Copper nanoparticles–containing tellurite glasses: An efficient SERS substrate

This work reports on a new application of CuNPs-containing tellurite glasses as surface-enhanced Raman scattering (SERS) substrate for detection of the molecular probe 2,2′-bipyridine (bpy) at low concentrations. First, the structural features of the glasses were analyzed by differential scanning ca...
