(a) SP-NRET efficiency in the stratified nanostructures with d′_m = 20 and 30 nm versus the spacer layer thickness. The highest SP-NRET efficiency is obtained at the thickness of the spacer layer equals to the silver films for each set. (b) Time resolved photoluminescence decay curves with two-exponential decay model at the donor emission wavelength for the donor-only layer (Alq3), the single layer structures with d_m = 60 and 90 nm and the stratified configurations with = 20 and 30 nm. Faster decay rates is observed in the stratified samples compared to the single layer structures. In the stratified structures, the thickness of silver layers and the spacer layer are deposited equally ( = ).
