Summary
Applying pressure enhances europium-based metal-organic frameworks
Area of Science:
- Materials Science
- Photochemistry
- Coordination Chemistry
Background:
- Europium-based metal-organic frameworks (MOFs) are promising for photoluminescent applications.
- Low luminescence efficiency, caused by inefficient ligand-to-metal energy transfer (LMET), hinders their practical use.
Purpose of the Study:
- To enhance the LMET process in europium MOFs.
- To trigger bright red light emission in Eu(BTC)(H2O)6.
Main Methods:
- Utilized a pressure-induced hydrogen bond enhancement strategy.
- Applied hydrostatic pressure up to 9.2 GPa.
- Conducted systematic photophysical characterization.
Main Results:
- Photoluminescence quantum yield increased from 19.2% to 69.1% at 9.2 GPa.
- Achieved bright red light emission with CIE coordinates (0.66, 0.31), meeting Rec. 2020 display standards.
- Enhanced hydrogen bonds optimized intersystem crossing and ligand-to-Eu3+ sensitization.
Conclusions:
- Pressure-induced hydrogen bond enhancement is an effective strategy to boost MOF luminescence.
- This method significantly improves LMET efficiency in europium-based MOFs.
- The enhanced MOFs show potential for advanced display technologies.
