Optical Spectroscopy Analysis Service—Horiba Fluorolog3 Spectrofluorimeter

Summary

The instrument is equipped with double-grating monochromator on both the excitation and emission sides coupled to a R928P Hamamatsu photomultiplier and a 450 W Xe arc lamp as the excitation source. Phosophorescence spectra can be acquired with the same instrument employing a pulsed Xe lamp. Lifetime measurements down to few nanoseconds can be achieved through Time Correlated Single Photon Counting (TCSPC) using pulsed nanoleds as excitation source. Absolute photoluminescence quantum yields can be measured by means of a Spectralon coated integrating sphere accessory (4", F-3018, Horiba Jobin Yvon) , fitted in the fluorometer sample chamber. The instrument can operate from 290 nm to 850 nm at variable temperature from 77 K to 600 K.
