Organic afterglow
Witryna1 gru 2024 · Organic afterglow emission includes two types, one is phosphorescence emission, in which the singlet state (S 1) transfers to the triplet state (T n, n ≥ 1) through the intersystem crossing (ISC) process, then the T 1 excitons deactivate to the ground state (S 0) via a phosphorescent radiation. Witryna28 paź 2024 · S peci cally, f or the typical organic afterglow s y stems (MEHPPV-base d nan oparticles), an 808. nm of laser with power density of a s high as 1 W/cm 2 was required t o excite adequate af terglow.

Witryna1 maj 2024 · This host-guest organic afterglow system constructed with Br-BID-Py and NMe 2-BID-Py is very special for two reasons. Firstly, the phosphorescence of the host is remarkably strengthened by doping of the guest. The intense afterglow originates from the triplet excitons of the host, which is different from the previously reports.
