WebPhosphorescence. A quasistable electron excitation state involving a change of spin state (intersystem crossing) which decays only slowly. In phosphorescence, light emitted by an atom or molecule that persists after the exciting source is removed. It is similar to fluorescence, but the species is excited to a metastable state from which a ...

Fluorescence, excitation and sensitized phosphorescence excitation spectra of three fluoropyridine vapors were measured. The S 1 → T 1 intersystem crossing yields were determined by a sensitized phosphorescence method. Main nonradiative process is shown to be the S 1 → S 0 internal conversion. The internal …
WebMay 20, 2024 · The T 1 state of PVA lied higher than S 1 state energetically, making the intersystem crossing forbidden. Therefore, the origin of phosphorescence was from TPEDB, and PVA was used as a non-emissive polymer matrix to stabilize TPEDB molecules. Fig. 5 DFT calculations of TPEDB-PVA polymeric materials.
