摘要：

A Cu2O superstructure is constructed through a recrystallization-induced self-assembly strategy. Single Cu2O 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 x 10(5)) due to the synergetic effect of vacancies defect-facilitated charge-transfer process and copper vacancies defect-induced electrostatic adsorption.
