WebApr 13, 2024 · An average fluorescence sensitivity enhancement factor of 27 ± 3 was obtained when the plasmonic array was added to the surface of high-index waveguides in Eagle2000 (see Figure 6c). One can clearly observe the effect of fluorescence enhancement by metals, particularly for the guide closest to the surface. WebThe fluorescence intensity is significantly enhanced by the slow photon effect of the photonic crystals when the emission wavelength overlaps with the blue band edge of the photonic stopband of the selected IOPC. This fluorescence enhancement improves the detection sensitivity of the sensor for Bi 3+ ions and its limit of detection is 0.1 nM.
