Fluorescence spectroscopy can be used to measure with high sensitivity the emission spectrum and lifetime of excited state of samples. Our Horiba Fluorolog-3 spectrofluorometer has a modular setup. The excitation source is a broadband 450 W Xenon lamp with emission ranging from UV to near-IR. Excitation spectra ranging from 240-600 nm and emission spectra ranging from 290-850 nm can be measured with good sensitivity.
Typically, samples are dissolved in high quality HPLC-grade solvent in ~10-5 M and the sample solution is analysed in a standard emission cuvette. Solid samples can also be analysed using a solid sample holder.
Fluorescence services is located at the Advanced Chemistry Laboratory (S7-04). For further information please contact mkmya@nus.edu.sg / +65 6601 1948 (Dr Mya Mya Khin).
For sample submission, about 4 mL of liquid samples or at least 100 mg of solids are needed. Please click to download the relevant request form:
