Solid-Surface Room Temperature Phosphorescence

2020
Luminescence can be defined as radiation emitted from atoms or molecules as they undergo a radiative transition from an excited state to a lower energy state. After the absorption of incident radiation, the emission of a photon during the radiative transition is called photoluminescence.

Laser Phosphoroscope and Applications to Room-Temperature Phosphorescence

Applied Spectroscopy, 2011
A simple phosphoroscope with no moving parts is described. In one scan the total luminescence, the long-lived phosphorescence, and the short-lived fluorescence can be determined. A 50% duty cycle excitation from a diode laser is used to excite the sample, and from the digitized waveform the phosphorescence is extracted from the off period, the total ...

Room Temperature Phosphorescence in Crystalline Iodinated Eumelanin Monomer

Chemistry – A European Journal
AbstractWe report the room temperature phosphorescence upon iodination on a crystalline eumelanin monomer with shielded hydroxyl moieties, ethyl 5,6‐dimethoxyindole‐2‐carboxylate (DMICE). Ultrafast intersystem crossing (ISC) is observed in the iodinated (IDMICE) as well as brominated (BDMICE) analogues of the eumelanin monomer derivative in solution ...
