Phosphorescence lifetime imaging
WebJun 1, 2024 · Signals from FITC, defined as phosphorescence lifetime over 2.1 ns, are shown in the second top panels, and merged images are shown in the panels at the bottom. Because more than 1 minute is needed to obtain a PLIM image, only 1 PLIM image is obtained before the administration of FITC. Bar = 100 μm. http://web.mit.edu/solab/Documents/Assets/So-Fluorescence%20spectrophotometry.pdf

Phosphorescence occurs when an excited molecule transits from the first excited singlet state, S1, into the first triplet state, T1, and returns from there to the ground state by emitting a photon [24]. Both the S1-T1 transition and the T1-S0 transition are forbidden processes. irish spelling of shannonWebOrganic room-temperature phosphorescence (RTP) materials are currently the focus of research in the field of bioimaging.
