Error in Figure and Text Correction
The original version of the manuscript [] contained two mistakes. The first one occurs in Figure 9a: the Ce 3d peak was not labeled on the survey scan report. The characteristic peaks of Ba MNN are at 901.1 and 888.4 eV, respectively, with some overlap with the broad peak of Ce 3d (880–920 eV). The corresponding correct results are shown in Figure 9a.

(a) Survey scan report of the BYP:Ce3+ crystal, and core-level XPS spectra of (b) O 1s, (c) Y 3d, (d) Ba 3d, (e) P 2p and (f) Ce 3d.
The second typographical error occurs in Figure 9f. A careful fitting was performed according to the cited reference [], and the results were presented in Figure 9f. Therefore, the relevant narratives in the manuscript [] regarding the Ce 3d HRXPS need to be corrected.
The text in Section 3.4 “The peaks are deconvoluted into three peaks under the best fit criteria to identify the valence states of Ce. Deconvoluted peaks are positioned at 885.1 eV, 888.7 and 891.5 eV in 3d5/2 and 897.1 eV, 900.9 and 904.4 eV in 3d3/2. The peaks found at binding energies of 885.1, 897.1 and 904.4 eV are assigned to Ce3+, while Ce4+ is allocated to the other binding energy values” has been corrected to: “These peaks are decomposed into two groups of peaks corresponding to the +3 and +4 valences of Ce, and the Ce +3 valence dominates in the crystal”.
Admittedly, the effect of Ba MNN spectral lines could not be completely eliminated when analyzing the Ce 3d peaks, which may have led to some deviations in fitting the peaks of the +3 and +4 valence states of Ce. However, this does not affect the conclusion presented in the manuscript [] regarding the simultaneous presence of both the +3 and +4 valence states of Ce ions in the BYP crystals. Apologies are extended to the Editor-in-Chief, the Editorial Office, and the readers of the journal for any inconvenience these two mistakes may have caused.
This correction was approved by the Academic Editor. The original publication has also been updated.
