Engineering Ultrastable Intrinsic Radicals: Graphene Quantum Dots With NIR-II Emission for Dynamic Deep-Tissue Bioimaging. [PDF]
Adv Sci (Weinh)Stable radicals are attractive for photonic and quantum information technologies but are often limited by instability. We stabilize intrinsic radicals in graphene quantum dots via 2D polymerization of perylene derivatives, where bilayer defect confinement suppresses quenching (100–500 K).

Quantum Dots in Graphene [PDF]
Universal Journal of Physics and Application, 2015 The paper reports on theoretical study of electron states for a quantum dot in a graphene monolayer. Discrete energy spectrum of quasiparticles inside the quantum dot is found. Energy levels and corresponding quasiparticle resonant wave functions are obtained, which allow calculating the local density of states inside the quantum dot. Some experimental

Spin States in Graphene Quantum Dots [PDF]
Physical Review Letters, 2010 We investigate ground and excited state transport through small (d = 70 nm) graphene quantum dots. The successive spin filling of orbital states is detected by measuring the ground state energy as a function of a magnetic field. For a magnetic field in-plane of the quantum dot the Zemann splitting of spin states is measured.
