Synthesis and Optical Manifestation of NiO-Silica Nanocomposite

Figure 5

PL spectra of NiO-silica nanocomposite prepared at three different temperatures (a)–(c), (a. u. means arbitrary units). PL spectra of pure silica prepared at the same temperature are shown by the dotted line for each sample. All the samples were excited at 4.12 eV (300 nm), and the data are taken in RT.
