Room temperature single photon generation at 1. 5 $\mu$ m from covalent dopant states of carbon nanotubes

Recent demonstration that oxygen dopant states covalently attached to the single-walled carbon nanotubes (SWCNTs) are capable of emitting single photons at room-T (RT) opens the possibility of building room-T electrically-driven single photon sources for quantum communication applications.$^{\mathrm{1}}$ The RT single photon generation was not observed only at wavelength beyond 1.3 $\mu$ m. Here in this work we demonstrate RT single photon generation at 1. 5 $\mu$ m from diazonium dopant states of (10,3) nanotubes. $^{\mathrm{1}}$ Ma, Xuedan. et al. Nature Nanotech. 2015, 10, 671
