- Integrated CNDs with rigid microconfinement within a flexible polymer matrix.
- Investigated the phosphorescence lifetime, stretchability, and optical stability of the resultant elastomers.
Main Results:
- Achieved maximum stretchability of up to 97% in the developed elastomers.
- Observed a phosphorescence lifetime of up to 1119 ms.
- Demonstrated tunable phosphorescence wavelengths across the visible spectrum and stable optical properties under various conditions.
Conclusions:
- The CNDs microphase engineering strategy successfully created high-performance stretchable phosphorescent elastomers.
