Abstract
Fluorescent lamp phosphors activated by complex ions(WO42- etc.), s2 configuration ions, Mn2+ or Eu2+ show broad band emissions. The spectral energy distribution(SED) shape for some selected phosphors has been discussed(1,2). We report a more generalized observation on these phosphors to deduce the SED features inherent in each of the activators. Every observed SED was plotted in terms of vs. wavenumber to compare it with the Gauss error function(I:Energy,I0:Maximum energy of SED).
