The blue-light-excitable phosphors play a crucial role in the high-performance white LEDs. Here, we report on two new Cu(I) coordination network materials as yellow-emitting phosphors prepared by suitably expanded π-conjugated triazole ligands. Upon blue-light irradiation, these complexes exhibit efficient solid-state emission and enhanced photostability. Through incorporating the yellow phosphor and a commercial blue-green powder (BaSi2N2O2:Eu2+) with a blue LED chip, the phosphor-converted LED devices display remarkable white emission properties. The experimental results demonstrate that the Cu(I) coordination network materials function as promising blue-light excitable phosphors with great application potential for full-spectrum white LEDs. |
