High-resolution CeL_γ4 emission spectra of CeF_3, Ce_2S_3, CeF_4, and CeO_2 have been measured using a multicrystal, multidetector spectrometer. The spectra exhibited substantial differences depending on the chemical environment of the Ce ions. By comparing the observed CeO_2 spectrum with the band calculations, we determined that the observed chemical effects of the main emission line were primarily attributable to the transitions of the Ce5p band; the high-energy tail at around 6.539 keV was assigned to the ligand p→Ce2s cross transition. Further, a key difference between CeL_γ4 and EuL_γ4 is discussed with reference to CeL_1- and EuL_1-X-ray absorption fine-structures (XAFS). Possible applications of CeL_γ4 emissions to material characterization are also suggested.
