Ytterbium/Yttrium Oxide Superlattices Sensing Strain under High Temperature

Abstract:

Rare-earth (RE) doped oxide materials are one of the interesting sensor materials potentially able to remote-sense strain inside an object under high temperature. In contrast to commonly investigated temperature-sensing methods of monitoring temperature-dependent luminescent characteristics of those doped RE ions, sensing strain under high temperatures, however, will be much difficult. This research develops a new strained superlattice that has the potential to sense strain under the high temperature environment, via monitoring the superlattice’s period-dependent luminescence.
