Abstract
The blue-light-excitable phosphors play a crucial role in the high-performance white LEDs.Here,we re-port on two new Cu(Ⅰ)coordination network materials as yellow-emitting phosphors prepared by suit-ably expanded π-conjugated triazole ligands.Upon blue-light irradiation,these complexes exhibit effi-cient 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 de-vices 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 applica-tion potential for full-spectrum white LEDs.
