Figure 3.

Normalized excitation (dots) and emission (solid line) spectra from varying spacer thickness from 10 nm to 75 nm. a) in the absence of the top Ag mirror (outside cavity) and b) in the strongly coupled system. The emission spectra are recorded upon excitation at 530 nm with normal measurement while the excitation spectra are collected at 700 nm at an angle of 22.5°.
