Harnessing long-lived visible phosphorescence to eliminate background interference from fingermark images

, 2021
Minimising background fluorescence can enhance the visible details of treated fingerprints. Here, a 4-tpt fingerprint powder exhibiting long-lived phosphorescence is applied to this end. The powder was found to suppress background fluorescence, including

Switching Singlet Exciton to Triplet for Efficient Pure Organic Room-Temperature Phosphorescence by Rational Molecular Design

, 2023
The design and regulation of phosphor are attractive but challenging due to the spin-forbidden intersystem crossing (ISC) process. Here, a new perspective on the enhancement of ISC was proposed and demonstrated. Different from current strategies, the ISC
