Abstract

The surface of anatase TiO2 nanocrystals with an average size of ~20 nm was modified by PMMA through γ radiation. The modified nanocrystals were investigated with photoluminescence (PL) and Fourier transform infrared (FTIR) spectra. A stable blue luminescence peak (~420 nm) can be observed for the modified anatase TiO2 nanocrystal.
