| Résumé: | © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. A Cu2 O superstructure is constructed through a recrystallization-induced self-assembly strategy. Single Cu2 O superstructure particle exhibits an outstanding surface-enhanced Raman spectroscopy performance with the limit of detection as low as 10-9 mol L-1 and metal comparable enhancement factor (8 × 105 ) due to the synergetic effect of vacancies defect-facilitated charge-transfer process and copper vacancies defect-induced electrostatic adsorption |
