WebNov 25, 2015 · Both amino boron dipyrromethene and rosamine derivatives are almost non-fluorescent in polar and apolar solvent. However, imine formation with salicylaldehyde on each fluorophore increases the fluorescence quantum yield by almost a factor of 10 (from 0.05 to 0.4). ... Correction for the refractive index was also applied. All spectra were ... WebIn general, an index of refraction is a complex numberwith both a real and imaginary part, where the latter indicates the strength of absorption loss at a particular wavelength—thus, the imaginary part is sometimes called the extinction coefficientk{\displaystyle k}.
