A modified Fourier transform (FT) Raman bench spectrometer designed for the detection of weak light emission in the 800–1700 nm wavelength region has been used to demonstrate the advantages of FT spectroscopy for measuring near-infrared photoluminescence spectra of lanthanide complexes with a good resolution and very good sensitivity. This apparatus has been tested with an ultraviolet laser source (325 nm) on three standard erbium complexes. The [sup 4]I[sub 13/2]→[sup 4]I[sub 15/2] emission of tris-(acetylacetonato) (1,10 phenanthroline) erbium [Er(acac)[sub 3](phen)], tris-(4,4,4,-trifluoro-1-(2 thenoyl)-1,3-butenedione) (1,10 phenanthroline) erbium [Er(TTFA)[sub 3](phen)] and tris(8-hydroxyquinolinato) erbium [Erq[sub 3]] has thus been recorded in solution and in the solid state and compared with literature. © 2003 American Institute of Physics.
