Figure 3: PL properties of the coupled QD-metamaterial system.
From: Dual-channel spontaneous emission of quantum dots in magnetic metamaterials
(a,b) Confocal mapping of the QD PL is shown for x-polarized and y-polarized detection, respectively. The metamaterial is situated in the lower right corner of the images, as indicated by the white-dashed lines. The scale bars are 6 μm. (c,d) Measured QD-PL spectra for x- and y polarization are plotted in blue and red, respectively. The reference QD PL (PL0) is shown in black. (e,f) Measured time-resolved QD PL (dashed lines) normalized to its maximum value and fitted exponential decays (solid lines) for x- and y polarization plotted in blue and red, respectively.
