Abstract
We report the formation of two-dimensional single crystalline nanosheets of Cu nanoclusters by complexation with Zn metal ion. The so-formed crystals, with augmented prompt photoluminescence and lifetime, exhibited delayed photoluminescence at room temperature with a quantum yield of 83.6 ± 1.3% and a lifetime of 26.4 ± 0.7 μs. The delayed photoluminescence lifetime was further increased to 145.0 ± 7.7 μs by surface functionalization of the nanosheets with 8-hydroxyquinoline. The surface complexation led to the generation of a new emitting channel in the crystal, which thus formed a single nanocomponent with dual channel emitting prompt and delayed near-white light.
