A Highly Sensitive “on-off” Time-Resolved Phosphorescence Sensor Based on Aptamer Functionalized Magnetite Nanoparticles for Cadmium Detection in Food Samples

Foods, 2020
Cadmium contamination is a severe threat to food safety. Therefore, the development of sensitive and selective cadmium detection strategies is urgently required. The elimination of background autofluorescence generated from the food matrix is critical to

An Ingenious Strategy to Stereoscopically Enhance the Phosphorescence Properties of Guest-Host Materials: Adding Metal Ions to Form Coordination with the Guest

, 2022
The host-guest doped strategy has been widely recognized as an effective method to construct room temperature phosphorescence materials. However, the advantage of the host in the doped system as a container that can hold the other components is ignored ...

Unified Analytical Framework for Understanding the Operational Stability of Blue Phosphorescent OLEDs: Quantitative Insights Into Exciton Recycling and Bimolecular Interactions

Advanced Functional Materials, EarlyView.
Blue phosphorescent OLEDs remain limited by poor operational stability. Here, a unified analytical framework integrating transient photoluminescence and magneto‐electroluminescence is developed to correlate intrinsic material photophysics with electrically driven degradation.
