spectral quantum efficiency of a fluorescent process

ημ(μ)

quotient of the total photon number of all wavelengths emitted from a specimen by a fluorescent process for an excitation at wavelength μ, and the photon number of wavelength μ reflected from the perfect reflecting diffuser identically irradiated and viewed

Note 1 to entry: The spectral quantum efficiency of the fluorescent process has unit one.

Note 2 to entry: This entry was numbered 17-1227 in CIE S 017:2011.
