Abstract
The O - K-spectra of α- and γ-Al2O3, β-Ga2O3 and In2O3 were measured with a high-resolution grating spectrograph using the method of electron excitation. The spectra were corrected for the nonlinear response of the photographic emulsions. A shift of the O - K-emission band edge of γ-Al2O3 to lower energy with respect to that of α-Al2O3 and a fine structure within all O -K-bands were observed for the first time. The details of the spectra are discussed in relation to the energy level diagrams, crystal structure, and chemical bond of these oxides.Keywords
