Abstract
Pure YH32-δ and Mg0.1Y0.9H2.92-δ exhibit large differences in their thermochromic properties.
Whereas the transmittance of YH32δ decreases by 9% to 36%, in Mg0.1Y0.9H2.92-δ it decreases by
64% to 83% between 30 °C and 160 °C. This thermochromic effect is caused by hydrogen
desorption upon temperature increase. The main difference between the two systems is that the
face-centered-cubic to hexagonal-close-packed phase transition between YH21-δ and YH32-δ is
absent in Mg0.1Y0.9Hx , i.e., the YHx stays cubic for all 2
