L-series emissions of manganese, iron and zinc oxides were studied using electron beam excitation and brilliant synchrotron radiation excitation. We showed that manganese and iron oxides show different Lβ/Lα intensity ratio due to their oxidized states, and excitation electron voltages, as were previously reported. On the other hand, we could not get any L-series emissions from those bulk samples when excited by normal incident high energy monochromatic X-rays, while samples of thin films and samples excited by glancing incident monochromatic X-rays showed clear emissions. It is suggested that the difference of Lβ/Lα intensity ratio due to the oxidized states mainly concerns with the Coster-Kronig transition ratio of the samples, while self-absorption effects should also deeply contribute the ratio, considering the experimental results.
