Fig. 2From: Formation and Luminescent Properties of Al2O3:SiOC Nanocomposites on the Base of Alumina Nanoparticles Modified by PhenyltrimethoxysilaneSelected spectral ranges of FTIR spectra of pristine alumina (spectrum 1), and phenyl-alumina before and after annealing at 400, 500, and 600 °C in the spectral ranges 400–1400 cm−1 (a), 1400–1775 cm−1 (b), and 2700–3200 cm−1 (c). Spectra are offset along the ordinate axis for clarityBack to article page
