LDOS enhancement and the normalized time-resolved PL spectra of QDs on Au nanoarray. (a) The x-position dependence of LDOS enhancement at the wavelength of 655 nm. An average LDOS enhancement of 64 times can be achieved. (b) The normalized time-resolved PL spectra of QDs with emission peak located at 655 nm. The emission rate of QDs increases from 0.0429 to 0.5 ns−1 by the existence of the Au nanoarray, showing an enhancement of 10.7 times.
