AB  - Processes taking place during hydrogen desorption from MgH2 thin films were investigated in as-prepared samples and samples modified by argon ion irradiation. Irradiation was used to produce well-defined defects with depth distribution. It was shown that the size, shape, and concentration of Mg nuclei formed during hydrogen desorption from MgH2 thin films depend on the characteristics and distribution of the induced defects. In as-prepared samples the shape of Mg nuclei is spherical, while in irradiated samples, it is highly irregular. Variations in sample colour were observed during hydrogen desorption and before the creation of Mg nuclei. DFT calculations showed that the observed variations in the optical properties of samples can be explained by changes in MgH2 electronic structure -the appearance of an H-vacancy band within the MgH2 energy gap.

AB  - Mg-Ni-H thin films were deposited by reactive magnetron sputtering. As-deposited samples were Mg-rich and annealed in air by two steps at T=220 and 290 degrees C in order to increase crystallinity. A reversible, thermochromic effect was detected when the crystalline yellow colour sample underwent a colour transition and changed its colour from yellow to red. The change in transmission spectra of the prepared thin films in visible range of spectra was induced by in situ heating setup. The continuous shifts of the transmission spectra at T=200 degrees C towards lower band gap was observed. Additionally, a photochromic effect was detected and confirmed by exposing the sample to visible light, as grey-coloured area appeared on the sample. (C) 2016 Elsevier B.V. All rights reserved.
