Mechanism and design of organic afterglow luminescent probes for cancer theranostics

MedMat
Organic afterglow luminescent probes (OALPs), characterized by their long-lasting luminescence after irradiation (by light, ultrasound, or X-rays) cessation, are pivotal tools in autofluorescence-free optical imaging. They exhibit ultra-low background noise interference, enhancing imaging sensitivity and ensuring clearer, more reliable imaging results.

Twofold rigidity activates ultralong organic high-temperature phosphorescence

Nature Communications
A strategy is pioneered for achieving high-temperature phosphorescence using planar rigid molecules as guests and rigid polymers as host matrix. The planar rigid configuration can resist the thermal vibration of the guest at high temperatures, and the ...

Well trap structures and bulk-nano environment luminescence centers in CaZnGe2O6:Tb3+ long afterglow phosphor

, 2012
A long afterglow phosphor CaZnGe2O6:Tb3+ has been prepared by using organic coated luminescence ZnO nanopowder through a high temperature solid-state reaction route. This new CaZnGe2O6:Tb3+ long afterglow phosphor sample emits the Tb3+ green fluorescence
