Physical review letters, 2013•APSA homogeneous linewidth of 85.6±4.4 kHz is reported in 60 nm Eu 3+ doped Y 2 O 3
nanocrystals at 1.3 K. This linewidth was measured by two-pulse photon echoes on highly
scattering powders using heterodyne detection. Spectral diffusion was also investigated by
three-pulse photon echoes and resulted in a limited broadening of the homogenous
linewidth of about 250 kHz over 120 μ s. Compared to achievable Rabi frequencies, in the
range of several MHz, these values show that rare earth doped nanocrystals can be useful …

A homogeneous linewidth of is reported in 60 nm doped nanocrystals at 1.3 K. This linewidth was measured by two-pulse photon echoes on highly scattering powders using heterodyne detection. Spectral diffusion was also investigated by three-pulse photon echoes and resulted in a limited broadening of the homogenous linewidth of about 250 kHz over . Compared to achievable Rabi frequencies, in the range of several MHz, these values show that rare earth doped nanocrystals can be useful for applications in optical quantum information processing.
