A new silver cluster emitting brightly blue phosphorescence

Abstract

A new hexanuclear silver (I) cluster (NC-Ag6) emits brightly blue phosphoresce with a lifetime of 22.4 μs and quantum yield (QY) of 22% under ambient conditions was synthesized. The film combined NC-Ag6 with yellow cerium (III)-doped yttrium aluminum garnet phosphors (YAG : Ce3+) displays chameleon-like emission, including white color, which is related to excitation-dependent Förster resonance energy transfer (FRET) between dual phosphors. The mechanoresponsive luminescence color of this silver cluster ranged from blue to green nearly without the loss of QY.
