Ultrasensitive SERS Detection by Defect Engineering on Single Cu2O Superstructure Particle. Issue 5 (28th November 2016) - Lin, Jie
Abstract : 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 × 10 5 ) due to the synergetic effect of vacancies defect‐facilitated charge‐transfer process and copper vacancies defect‐induced electrostatic adsorption.
