We present an overview of recent investigations of photopolymerizable nanocomposite photonic materials in which, thanks to their high degree of material selectivity, recorded volume gratings possess high refractive index modulation amplitude and high mechanical/thermal stability at the same time, providing versatile applications in light and neutron optics.(More)
We demonstrate holographic patterning of semiconductor CdSe quantum dots in photo-polymerizable monomer films for constructing cm-size transmission volume Bragg grating structures. Fluorescence and confocal Raman imaging confirm holographic assembly of CdSe quantum dots in the formed polymer. We observe the diffraction efficiency near 100% from the grating(More)
