Carbon Nanotube-Based Nanophotonics

• Ultra-clean SWCNTs with enhanced emission dynamics:

1. Two orders of magnitude longer spontaneous emission time (T1) compared to previously reported experiments.
2. Measurement of exciton dephasing time (T2) for the first time in the time domain- 4 times longer compared to previous results. 

It is published in Nature Communications and highlighted in Advanced Science News
