Spectrum absorption and luminescence methods were used to investigate the peculiarities of optical properties of compound material consisting of nanoporous silica with impregnated gold nanoparticles soaked in rhodamine 6G ethanol solution. One possible explanation for the phenomenon of increasing of absorption near plasmon resonance frequency and rhodamine 6G absorption band is given.

We have presented the results of our investigation concerning adsorption in porous glass (PG). Chemical adsorption of gas molecules is due to indicator substances which were deposited from solution on the surface of pores. Physical adsorption of organic molecules is due to OH-adsorption centres which are always arranged on the surface of PG at room temperature. Adsorption processes were investigated with infrared spectroscopy.
