Near IR capability of the FluoroLog

The SPEX FLUOROLOG spectrofluoro-meter, with its modular flexibility, gives choice of gratings, detectors, and other accessories. The standard FLUOROLOG configuration has an R928P photomultiplier tube in an L-format, and is sensitive out to ~ 850 nm. For near-IR fluores-cence measurements, an optional solid-state de-tector (DSS-IGA020L) can be substituted for the R928P, or mounted on the T-side of the sample compartment. The DSS-IGA020L is an InGaAs detector, with sensitivity to ~1700 nm. This Application Note demonstrates the ability of the FLUOROLOG to detect fluorescence emissions in the near-IR.

A liquid-N2-cooled DSS-IGA020L In-GaAs detector was used on the T-side of a FLUOROLOG-321 (single emission mono-chromator). The gratings groove density was 600 grooves mm1, blazed to 1.0 m. Samples were Nd-doped phosphate laser glass, and Er2O3 powder. The integration time was 0.2 s. Scan-ning parameters are in Table 1 (see back).

Figure 1 (Nd-doped glass, below) shows clear peaks in the red and near-IR regions. Fig-ure 2 (on back) shows spectra for Er2O3 powder in a Model 1933 solid-sample holder. A 780-nm cut-off filter was used in the emission spectrum. Obvious near-IR bands are visible at ~1000 nm and ~1500 nm.

The FLUOROLOG is a sensitive in-strument for all fluorescence applications in the liquid or solid state. With its ability to add detec-tors easily, the full range of fluorescence, from UV to near-IR, is available for all your fluores-cence needs.
