Abstract
With a two-crystal vacuum spectrometer equipped with beryl crystals, t he Cu Lalpha emission spectra in fluorescence have been measured for s elected copper compounds Cu2O, CuO, CuCl, CuBr, Cul, CuF2, CuCl2, CuBr 2, CuF2.2H2O, CuCl2.2H2O and Cu3P, and alloys alpha-Cu+35%Zn and Cu+2% Be. The measured spectra are grouped into three classes. The first cla ss comprises the spectra of alloys, which consist of a single broad ba nd similar to that of Cu metal. The second class includes the spectra of monovalent copper compounds, which are composed of a prominent peak and its high- and low-energy structures. To the third class belong th e spectra of divalent copper compounds, which consist of a strong peak accompanied with a characteristic dip and hump on the high-energy sid e. The Cu Lalpha emission bands of Cu2O, CuCl and CuBr are compared wi th available XPS spectra and theoretical Cu-3d-DOS.
