Phosphorescent perylene imides [PDF]

Chemical Communications, 2012
Asymmetrically substituted perylene imide derivatives PIa and PIx display phosphorescence in glassy matrices at 77 K. The lifetime is 49.0 ms for PIa and 13.5 ms for PIx. The triplet energy is 1.79 eV for PIa and 1.68 eV for PIx as confirmed by sensitization experiments of the C(60) triplet.

Benchmark Study on Phosphorescence Energies of Anthraquinone Compounds: Comparison between TDDFT and UDFT

Molecules, 2023
Phosphorescent material is widely used in light-emitting devices and in the monitoring of cell phenomena. Anthraquinone compounds (AQs), as important phosphorescent materials, have potential applications as emitters for highly efficient organic light ...

Matrix‐free room‐temperature phosphorescence graphitic carbon nitride quantum dots based on halogen bond interactions for security applications

Nano Select, 2022
Herein, we first designed a one‐step strategy to achieve matrix‐free room temperature phosphorescence (RTP) materials by low temperature solid phase synthesis, using sodium citrate as carbon source and urea as nitrogen source.

Coherent energy migration in solids: Determination of the average coherence length in one‐dimensional systems using tunable dye lasers [PDF]

, 1976
The coherent nature of energy propagation in solids at low temperatures was established from the time resolved response of the crystal to short optical pulses obtained from a dye laser (pumped by a nitrogen gas laser).

Persistent luminescence in Eu2+-doped compounds : a review [PDF]

, 2010
In 1996, Matsuzawa et al. reported on the extremely long-lasting afterglow of SrAl2O4:Eu2+ codoped with Dy3+ ions, which was more than 10-times brighter than the previously widely used ZnS:Cu,Co.

Induction of long-lived room temperature phosphorescence of carbon dots by water in hydrogen-bonded matrices

Nature Communications, 2018
A long phosphorescence lifetime is desirable for imaging and detection, however, phosphorescence is often quenched in aqueous environments limiting applications. Here, Li et al.
