Surface enhanced fluorescence from corroles and SERS studies of explosives using copper nanostructures
We report the deployment of complex copper nanoparticles (NPs) and nanostructures (NSs), fabricated in a single step by ultrafast laser ablation of copper (Cu) in corroles/chloroform solutions, for surface enhanced fluorescence and surface enhanced Raman scattering studies (SERS). The characterization was performed by TEM, SAED, UV-visible absorption, and SEM techniques. Florescence enhancement of five orders in magnitude was obtained from corroles conjugated to Cu complex NPs. Cu NSs were utilized to record the SERS spectra of adsorbed Rhodamine 6G and explosive molecules of 5-amino-3-nitro-1,2,4-triazole and 1,1-diamino-2,2-dinitroethene. The estimated enhancement factors were in the range of 10(6)-10(8). (C) 2015 Elsevier BY. All rights reserved.
