(Invited) Photostability of Core-Shell Structures at Low Temperature

The use of carbon nanotubes as single emitters is currently developing. Being made only of surface atoms carbon nanotubes are very sensitive to their environment. A fingerprint of this sensitivity is the variation with time of their emission intensity (blinking) and energy (spectral jitter) in low temperature experiments. To improve the stability of nanotubes, we have synthesized core-double shell structures where two shells of polymers are rolled around the nanotube [1]. Here, we will show the influence of these shells on the stability of both the emission intensity and energy [2]. [1] L. Orcin-Chaix et al, Journal of Material Chemistry C 6, 4786 (2018) [2] L.
