measurements were performed with a PANalytical Empyrean X-ray diffractometer
equipped with a 1.8 kW Cu Kα ceramic X-ray tube (1.5418 Å)
and a PIXcel3D 2 mm × 2 mm area detector, operating
at 45 kV and 40 mA. The reflections were collected at room temperature
using a parallel-beam geometry and symmetric reflection mode, in a
2θ range of 15–70° with a step time of 450 s and
a step size of 0.1°, repeating the measurement four times to
reduce the signal noise. The XRD results were analyzed using HighScore
4.1 software (PANalytical).
