Phosphorescence lifetime imaging
WebOct 28, 2024 · As long as the burst duration is shorter than the phosphorescence lifetime the excitation efficiency will increase in proportion to the number of pulses within the burst. Multi-pulse excitation has been used for multiphoton phosphorescence imaging earlier but bh were first to apply it to TCSPC PLIM. The principle is shown in Fig. 2.2. The ... WebDec 5, 2024 · Taking advantage of the large Stokes shift and long lifetime of phosphorescence, there are three types of phosphorescence imaging methods: (1) Different-channel phosphorescent imaging. As the phosphorescence has a Stokes shift. Compared with the fluorescence, it can be collected by different filters bands for …
