Abstract

Titanium dioxide nanoparticles (NP) and nanofibers (NF) were incorporated from polymeric gels into porous glasses. Two types of glasses A and B with different porosity were chosen for measurements. Optical absorbance and photoluminescence spectra of the samples were measured at the range of 200–1100 nm and 370–800 nm correspondently before and after TiO₂ incorporation. The enhancement of TiO₂ photoluminescence (PL) and short-wave shift of peaks for samples A and B was found. The obtained results are explained by quantum confinement effects.
