(Top) Representative Co Kβ emission spectra collected in 20 min for bulk samples (LixCoO2 crystals, with different x content: 0.99, 0.66 and 0.46; the blue line corresponds to the signal collected for a pellet sample, while the others to signals obtained by measuring single crystals). (Bottom) Energy resolution and dispersion for several emission lines reachable with the Si 333, Si 444, Si 555 and Si 888 reflections empirically measured. |
