In addition, this technique simulated the excitation and fluorescence emission of the DPA-Tb using a 4-level energy model, and solved the dynamic transient rate equations to predict the temporal behavior of the DPA-Tb emitted fluorescence. Excellent agreement between the experiments and the simulation were found. This technique has the potential to provide a more accurate value for the fluorescence lifetime values. In addition, with the use of asymmetric excitation waveforms, the dynamic transient rate equation analysis may allow for detailed studies of selected transfer mechanisms in a wide range of other spectroscopic applications including rare-earth solid-state lasing materials and biological samples.The signal from the PMT was then sent to a 500 MHz oscilloscope (Lecroy, Waverunner LT 344), whose specifications are in Table 6.1. The trigger ... This monochromator could be used in a manual or a computer-controlled mode. The controlanbsp;...
