Polarized fluorescent nanospheres

Optics Express, 2010
Fluorescent beads (nanoparticles, nanospheres) are commonly used in fluorescence spectroscopy and microscopy. Due to the random distribution of dye and high dye to nanoparticle ratio, the fluorescence polarization observed from the beads is low. Therefore beads are not used for polarization study.

Saturation effects in polarized fluorescence photobleaching recovery and steady state fluorescence polarization

Biophysical Journal, 1994
The time-resolved anisotropy produced in polarized fluorescence photobleaching recovery experiments has been successfully used to measure rotational correlation times in a variety of biological systems, however the magnitudes of the reported initial anisotropies have been much lower than the theoretically predicted maximum values.

Light emission from dye-doped cholesteric liquid crystals at oblique angles: simulation and experiment [PDF]

, 2012
Dye-doped cholesteric liquid crystals with a helical pitch of the order of a wavelength have a strong effect on the fluorescence properties of dye molecules. This is a promising system for realizing tunable lasers at low cost. We apply a plane wave model

Dynamics of Fluorescence Polarization in Macromolecules [PDF]

Proceedings of the National Academy of Sciences, 1972
Reexamination of the theory of fluorescence time dependence owing to rotational diffusion of rigid macromolecules reveals deficiencies or hidden restrictions in each of the previous treatments. The correct master equation has five exponential decay terms, with preexponential factors that depend upon the diffusion constants and, in a completely ...

Polarization effects on fluorescence measurements [PDF]

Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1975
Polarization effects on fluorescence measurements are a function of four independent variables. The first is F, the polarization ratio of the exciting light which reaches the sample. The second is r, the emission anisotropy of the sample, which is the polarization "response" of the sample to plane polarized exciting light.
