Optical properties and degradation mechanism of magnesium-niobium thin film switchable mirrors

“…On the other hand, the switching durability of the Mg-Nb mirror is inferior to the Mg-Ni system mirror. 6) We can extend the switching durability by increasing the thickness of the Pd or inserting a metal buffer layer; 16) however, this will also reduce the transmission. It is important to choose the most suitable thickness of the Pd to increase its lifetime.…”

Mg-Based Thin Films as Model Systems in the Search for Optimal Hydrogen Storage Materials

“…Optical properties of Pd-capped MgyNi1-y thin films for the Mg-rich side of the Mg-Ni system (0.7<y<0.9) was also investigated by Yoshimura et al [79]. The films showed much better optical transmittance upon hydrogen exposure compared to the stoichiometric Mg2Ni compound (indicated in Figure 12 by dashed, vertical line for y = 0.667), contrary to the results obtained by Gremaud et al which showed rather constant transmittance in the 0.7<y<0.9 region ( see Figure 12 [77]).…”

Metal hydrides for smart window and sensor applications

“…Using a 40-nm-thick Mg-Ni alloy thin fi lm capped by a 4 nm Pd thin fi lm, an optimal transparency is found at 85 mol% Mg concentration. 22 The Pd layer protects it from oxidation and serves as a catalyst for the hydrogen dissociation reaction to take place at room temperature. Remarkably, the optimal transmittance takes place far beyond the composition at which the Mg 2 NiH 4 phase is formed.…”
