Triplet Excimers and the Heavy-Atom Effect Enable Bright Room-Temperature Phosphorescence and X-ray Scintillation in an Yttrium-Phenothiazine Coordination Polymer
The design of room-temperature phosphorescent materials that simultaneously offer long lifetimes and high exciton utilization remains challenging. Herein, through a solvothermal reaction between 5-(5,5-dioxido-10H-phenothiazin-10-yl)isophthalic acid (H2PTZO) and Y(NO3)3·6H2O, an yttrium-based coordination polymer, {Y...
