On magnetic red shift of absorption edge in EuO

Solid State Communications, 1985
Abstract The experimental data on the magnetic red shift of absorption edge in EuO are analysed. It is shown that the electron-impurity interaction and the strong perturbation of electron states due to s -ƒ exchange interaction should be taken into account to explain the experimental data.

Estimating biomass of rice in farmers' fields by red-edge indices

2014 6th Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing (WHISPERS), 2014
Biomass is an important parameter that has a decisive influence on the final yield. Destructive measurements of biomass are time-consuming and labor-intensive. Proximal sensing methods using field spectrometers offer indirect observation and estimation of biomass.

Non-exponential decay of indole fluorescence — the red-edge effect

Biochemical and Biophysical Research Communications, 1974
Abstract The fluorescence of indole in glycerol decays exponentially at both 22° and −80°C for 280 nm excitation. Under 296 nm excitation the 22°C emission decay is exponential, but at −80°C, a second shorter lived (1.3 ns) component is also detected. The relevance of this result to the determination of protein fluorescence lifetime is described.

Application of red edge variables in winter wheat nutrition diagnosis

IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004
Remote sensing offers the potential to determine rapidly the physiological condition of crop over large areas. Canopy reflectance data selected at key growth stages of winter wheat were analyzed. It indicated that winter wheat growth phonological changes can be evaluated by red edge variables (REV) characteristics.

Red-edge excitation fluorescence spectroscopy of proteins in reversed micelles

Journal of Protein Chemistry, 1994
The dependence of fluorescence emission maxima of L-tryptophan and single-tryptophan-containing proteins (ribonuclease T1, melittin, and parvalbumin) on excitation wavelength has been studied in reversed micelle systems of sodium bis(2-ethyl-1-oxyl) sulfosuccinate (AOT).

Site-selective Red-Edge effects.

Methods in enzymology, 2009
Observation of Red Edge effects is the basis of unique methodology that allows combination of site-photoselection with dynamics of molecular relaxations. The important dynamic information on molecular level can be obtained even by simple recording of steady-state fluorescence using the lifetime as the time marker.
