18.03.2013 Measurement of the luminescence lifetime with the nanosecond range using the Fluorolog-3 spectrofluorimeter

Posted in Новости

The luminescence lifetime of the fluorescein solution was measured using the Fluorolog-3spectrofluorimeter. . The luminescence excitation of the sample was generated by the LED with 495 nm wavelength and with the pulse duration less than 1.5 ns. The luminescence was obtained at the wavelength λ_em=517 nm. Received luminescence lifetime is τ=3.96±0.01 ns (table lifetime of the fluorescein is 4.0 ns).
