(a) and (b) Side view schematics of a nanodiamond placed near an apex of an SNW and in the gap between two end-to-end aligned SNWs. (c)and (d) Top view schematics of the same structures as in (a) and (b), respectively. SNW: silver nanowire, ND: nanodiamond.
Simulation results showing decay rate enhancements (in color scale) as a function of position and orientation of the dipole inside the nanocrystal. is obtained for the same dipole emitter in a nanodiamond placed on a glass substrate without SNWs. (a) and (b) Plots of for dipole emitters lying in the xy-plane (z = 0 nm) in a nanodiamond, close to one SNW and in the gap between two end-to-end aligned SNWs, respectively. The orthogonal dipole orientations used for the simulations are indicated in various plots.
(a)-(c) AFM images of silver nanowires and a single NV-center contained in a nanodiamond, which is indicated by the arrows in respective figures. (d) Emission spectrum for the nanodiamond indicated in (a). ZPL: zero phonon line. (e) and (f) Fluorescence images of the nanowire-nanodiamond systems shown in (b) and (c), respectively, where the excitation point is the nanodiamond containing a single NV-center. (g) Autocorrelation measurement data and a model fit to the data obtained for emission from the nanodiamond indicated in (a). (h) and (i) Graph showing the measurement data for the change in lifetime when the nanodiamond containing NV-center is moved near to silver wires as shown in (b) and (c), respectively. (c), (f) and (i) correspond to system 2 in Table I , whereas the other figures correspond to system 1 in Table I .
Spontaneous emission -factor for coupling to the two SNWs, which are aligned end-to-end. Blue and red curves show β-factors for coupling to the left ( ) and the right ( ) SNWs, respectively. Black curve shows the total β-factor ( ).
Decay rate enhancements due to coupling to one SNW and two end-to-end aligned SNWs, normalized to the decay rate of the NV-centers without SNWs.
