Line Plot from Scientific Research

Original T1 time as a function of the density of noise spins on the diamond surface, which was assumed to have a 0.1 nm thick shell (intrinsic thickness of spin on NDs). To have an average T1 of 223.9 s for NDs with a diameter of about 27.9 nm, this density of electron spins is noise= 1.9/nm3.
