Multi-functioning material compositions, structures incorporating the same and methods for detecting ageing in luminescent material compositions

A multi-functional material composition comprising a zirconia host and containing a luminescent lanthanide oxide additive, in particular dysprosia (Dy2O3), wherein the lanthanide oxide additive is effective both in stabilizing the zirconia and providing for luminescent temperature sensing, and a met...

Beschreibung
Zusammenfassung:	A multi-functional material composition comprising a zirconia host and containing a luminescent lanthanide oxide additive, in particular dysprosia (Dy2O3), wherein the lanthanide oxide additive is effective both in stabilizing the zirconia and providing for luminescent temperature sensing, and a method of determining a remaining useful life-time for the luminescent material composition from the proportion of a monoclinic phase (m) in the material composition.
