Spectrum with peaks labelled taken with an Ocean Optics HR2000 spectrometer [1] of ambient light provided by fluorescent lamps. Spectrum taken by me (apparently en:user:Deglr6328). The spectrometer appears to be about ~.6 to .8 nm off judging from the location of known peaks. Interpretation of spectral peaks has been done using the NIST database of spectra for mercury [2] and an article on fluorescent light phosphors [3]. This spectrum is not calibrated for intensity.

Peak number Wavelength of peak (nm) Species producing peak Actual line location (nm)
1 405.4 mercury 404.656
2 436.6 mercury 435.833
3 487.7 terbium from Tb3+ ~485 to 490
4 542.4 terbium from Tb3+ ~543 to 544
5 546.5 mercury 546.074
6 577.7 likely terbium from Tb3+ or mercury 576.960 for Hg or ~578 for Tb
7 580.2 mercury or terbium from Tb3+ 579.066 for Hg or ~580 for Tb
8 584.0 possibly terbium from Tb3+ or europium in Eu+3:Y2O3 ~580
9 587.6 likely europium in Eu+3:Y2O3 ~587
10 593.4 likely europium in Eu+3:Y2O3 ~593
11 599.7 likely europium in Eu+3:Y2O3 ~598
12 611.6 europium in Eu+3:Y2O3 ~611
13 625.7 likely terbium from Tb3+ ~625
14 631.1 likely europium in Eu+3:Y2O3 ~630
15 650.8 likely europium in Eu+3:Y2O3 ~650
16 662.6 likely europium in Eu+3:Y2O3 ~661
17 687.7 likely europium in Eu+3:Y2O3 ~687-688
18 693.7 likely europium in Eu+3:Y2O3 ~693
19 707 and 709 likely europium in Eu+3:Y2O3 ~707 and ~709
20 712.3 likely europium in Eu+3:Y2O3 ~712
21 760.0 likely argon 758.9315 or 763.5106 (??)
22 811.0 likely argon 811.531
  • Note that the terbium could be either Tb3+, Ce3+:LaPO4 or Tb3+:CeMgAl11O19.

Source Derivative work made by combining this image by User:Deglr6328, File:Fluorescent lighting spectrum peaks labelled.svg, with this photo by me (User:Zaereth), File:Helical fluorescent lamp spectrum by diffraction grating.JPG. The purpose is to both add some color to the photo and help readers visualize the colors of the peaks.
