3 Terms and Definitions
GB/T 13966 and established in the following terms and definitions apply to this section.
3.1
Molecules (atoms or ions can also be) absorb the energy transition to an electronic excited singlet state, total spin quantum number and then return to the same group
Electromagnetic radiation emitted when the state.
3.2
At a fixed emission wavelength conditions, the fluorescence intensity with excitation wavelength curve.
3.3
Under fixed conditions of excitation wavelength, the fluorescence emission intensity as a function of wavelength curve. Fluorescence spectra in the usual sense refers to fluorescence emission spectrum.
3.4
Sample to produce fluorescence excitation wavelength of incident light, represented by lambdaex.
3.5
Fluorescence wavelength of the emitted substance, but also the detection of the fluorescence measurement wavelength used in the sample, expressed by lambdaem.
3.6
Material and emission wavelength difference between excitation wavelength (emission wavelength substance is always greater than the excitation wavelength).
