Effects of orientation and composition on the extrinsic contributions to the dielectric response of relaxor-ferroelectric single crystals
The dielectric response of (1−x)Pb(Zn1/3Nb2/3)O3-xPbTiO3 (PZN-x%PT,4.5x12) single crystals is reported for ac field amplitudes up to ~2  kV/cm at 1 kHz. The Rayleigh law is used to stu...

We demonstrate the influence of spectral linewidths of individual donor-acceptor couples on energy transfer efficiency in semiconductor nanocrystal–DNA–organic dye conjugates. Temperature-dependent single molecule and ensemble spectroscopy data are analyzed using the Förster theory within the macroscopic and microscopic approaches. The results obtained evidence on the importance of the spectral overlap between emission of a single donor and absorption of a single acceptor in its close vicinity, which determines the microscopic resonance and transfer efficiency between individual neighbors. This realization poses important implications on the applicability of ensemble spectral overlap for the analysis of distance dependencies of nanoscopic objects. ©2009 American Institute of Physics
