The normalized fluorescence intensity (y-axis) and the wavelength (x-axis) are used as axes. The wavelength range is 360 nm to 575 nm. The integration time is set to 5 ns.</p> 2014-07-02 03:11:53 Spectrum analysis techniques Fluorescence spectroscopy Time-resolved fluorescence spectroscopy spectrophotometry fluorophotometry Fluorescence spectrometry spectra gates 20 35 50 65 75
