Figure 7From: Angular shaping of fluorescence from synthetic opal-based photonic crystal Fluorescence spectra of photonic crystal samples with different spectral positions of stop zones. Numbering of spectra 1 and 2 corresponds to the numbering of samples. Spectrum 3 is fluorescence of a soda lime glass slab. Spectra 1′ and 2′ are reflectance spectra of samples 1 and 2, respectively (plotted not to scale with fluorescence).Back to article page
