S-Heptazine N-ligand based luminescent coordination materials: synthesis, structural and luminescent studies of lanthanide–cyamelurate networks

“…For Dy-Cy, the emission lifetime is 3.48 μs at 298 K, which is in the usual range for Dy 3+ -containing coordination polymers (2.7 to 25.9 ms). [92][93][94] For Er 3+ coordination polymers, three regions are expected to show emission signals: visible (350-700 nm), near-IR (900-1400 nm), and above 1400 nm. [95][96][97] The emission of Er-Cy in the 350-700 nm region is readily observed (Fig.…”
