Fig. 3: Enhanced CQD fluorescence of the 2D PhC phosphor.
From: Structurally engineered colloidal quantum dot phosphor using TiO2 photonic crystal backbone
a, b Measured CQD fluorescence spectra for a the 2D PhC phosphor and b the reference phosphor, both measured as a function of the excitation wavelength. c Emission enhancement factor plotted as a function of the excitation wavelength. Also shown for comparison is the measured transmittance spectra. d CQD fluorescence intensity at the resonance wavelength, measured as a function of the polarization angle of excitation photons. The line is for reference. The inset is for identifying the polarization angle with respect to the square-lattice PhC pattern
