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 |

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 |

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.
