A digital Microscope VHX-6000 by Keyence was used for microscopic images of the MIL-116 (Ga)powder and films. A universal zoom lens VH-Z100UR with a magnification range of 100x to 1000x was used. The XRD data was recorded using Rigaku MiniFlex diffractometer with a 600 W X-ray generator (Cu Kα X-ray radiation, λ = 1.54 Å). The Bragg-Brentano geometry was used in the 3.00-40.00°2θ range along the step size of 0.02 °.
