Visualized Real-Time Flexible High-Temperature Sensing in Eu3+/Tb3+-doped Y2Mo3O12 Negative Thermal Expansion Material Film

Visualized real-time flexible high-temperature sensing in Eu 3+ /Tb 3+ -doped Y 2 Mo 3 O 12 negative thermal expansion (NTE) thin films achieved multiple naked-eye color spans that depended on different energy transfer between Eu 3+ /Tb 3+ -doped NTE materials.
