Phys. Rev. B 77, 165420 (2008) [5 pages]Quantum size effect on 67Zn-NMR measurements of ZnS nanoparticlesReceived 14 February 2008; published 18 April 2008 An unusual nuclear magnetic resonance phenomenon is present to demonstrate the quantum size effect of ZnS clusters with its length scale properly estimated within 4 nm from the 67Zn-NMR measurements. Strong quadrupole interaction induced from the quantum size effect is proposed to explain this phenomenon. A simple calculation of the electric field gradient by direct summation over all lattice points was performed to demonstrate this size effect phenomenally, and the result is in good agreement with the experimental observation. © 2008 The American Physical Society URL:
