Megjegyzések:	The influence of gold nanoparticles (AuNPs) on the decomposition of two widely used types of photoinitiators (Bis (.eta.5-2,4-cylcopentadien-1-yl)-bis (2,6-difluoro-3-(1H-pyrrol-1-yl)-phenyl) titanium/Irg784/and 2,2-Dimethoxy-2-phenylacetophenone/In2/) was investigated in this work, both, in simple toluene solutions or solutions with AuNPs, as well as in SiO2 nanoparticles and AuNPs containing monomer acrylate nanocomposites during photopolymerization. These processes are important for efficient, one-step creation of photonic structures by holographic recording based on polymer nanocomposites containing AuNPs with plasmonic properties. Analysing such processes, activated by irradiation with wavelengths of 532?nm and 325?nm, their efficiency and parameters of grating recording, as well as examining the related multistep photopolymerization processes by IR and UV?vis spectroscopy the influence of AuNPs on the decomposition of the photoinitiators was shown and explained by the mechanism of complex formation. Thereby, it is concluded that by combining the type of initiator, polymer matrix components, and illumination conditions the decomposition of initiators can be manipulated, that in turn affect the resulting optical modulation characteristics and the efficiency of the photonic elements recording in a one-step process.
