摘要：

The surface of ZnO and anatase TiO2 nanocrystals was modified by PMMA through gamma radiation. The modified nanocrystals were investigated with photoluminescence (PL) and Fourier transform infrared (FTIR) spectra. A stable blue luminescence peak (similar to 420 nm) can be observed for the modified ZnO and anatase TiO2 nanocrystals. The intensities of luminescence of the modified ZnO and anatase TiO2 in aqueous solution are very stable, even unchanged after storage time of one month. (c) 2006 Elsevier B.V. All rights reserved.
