PhD: Photochromism in Oxyhydrides
Recently, the unique photochromic properties of YOH were discovered. Unlike other photochromic materials, these materials darken over a large fraction of the solar spectrum upon illumination. The contrast is large, and UV is not required for the excitation. This makes these materials optimally suited for the inside of double glazed window panes. However, the bleaching of the photodarkened material is slow. To solve this problem we need to know more about the mechanism of the effect. Hence, the aim of the project is an in-depth study to elucidate the photochromic transition by a variety of thin film characterisation techniques. At the same time, we will further explore the properties of other oxyhydrides using combinatorial thin film techniques with sputtering and pulsed laser deposition.
