H. Hanzawa et al., MEASUREMENT OF DECAY TIME FOR THE NV CENTER IN IB DIAMOND WITH A PICOSECOND LASER-PULSE, DIAMOND AND RELATED MATERIALS, 6(11), 1997, pp. 1595-1598
The luminescence decay time of the NV center in synthetic Ib diamonds
has been measured using the picosecond excitation system at room tempe
rature and ca 5 K. The decay profile with two exponential components o
f 2.0+/-0.1 ns and 8.0+/-0.2 ns has been obtained at room temperature.
Around 5 K, the long decay component becomes slightly longer. The dec
ay times observed at 637.5 nm of the zero-phonon line and at 670 nm in
the phonon-side band are independent of wavelength. This value is com
pared with the previous value observed by other workers. (C) 1997 Else
