Fluorescent intensity spectrum
Web14 hours ago · Fluorescent response time is a crucial factor for probe in practical applications, which reflects the sensitivity of probes to some extent. To this end, the experiment of time-response of L fluorescence detection of H 2 S was explored. After about 60 s, the fluorescence intensity of probe increased more than 10 times (Fig. 1 F). WebJan 30, 2024 · A fluorescence example would be if a 3s electron of a vaporized sodium atom is excited to the 3p state by absorption of a radiation at wavelength 589.6 and 589.0 nm. After 10 -8 s, the electron returns to ground state and on its return it emits radiation of the two wavelengths in all directions.
