Sub-Nanosecond Fluorescence Lifetimes Using Light Pulses Of Several Nanoseconds Width

[Full Text]



Yaser A. Yousef



Keywords: Fluorescence lifetime, benzimidazole, -tocopherole, fluorescence decaytime, pesticides, TCSPC.



Abstract: This work demonstrates the possibility of obtaining fluorescence lifetimes in the sub-nanosecond timescale using excitation light pulses with few nanoseconds width. Measured and calculated fluorescence lifetime values where confirmed using more sophisticated systems with pico-second and-femto second pulse width excitation sources. For demonstration purposes the variation in fluorescence lifetimes for -tocopherol in polar and nonpolar solvents is presented.
