3.4. XRD of the Samples During the Aging ProcessThe X-ray diffraction (XRD) patterns of the samples during aging under different conditions and after 200 days of aging are presented in Figure 8. The results reveal that all samples exhibit a prominent (200) diffraction peak near 22°, along with characteristic peaks corresponding to the 110 plane (approximately 15°) and the 040 plane (near 34°).

It was recently found that the optical field fluctuations in self-defocusing media can be described by sound waves propagating in a two-dimensional photon fluid. This photon fluid is controlled by the driving beam and serves as the background in which the sound waves can experience an effective curved spacetime, such that it provides a new platform of studying analog black holes.
