新合成的两个超小铜纳米团簇[Cu-3(mu(3)-H) (mu(2)-dppy)(4)](ClO4)（2)(1)）和[Cu-4(mu(4)-H)(mu(2)-dppy)(4)(mu(2)-Cl)(2)](ClO4) (2) （dppy =二苯基-2-吡啶基磷化氢）表现出超亮黄色和黄绿色的室温磷光（RTP）发射，量子产率分别为71.8%和63.5%。因此，纳米团簇1首次作为单组分荧光粉应用于具有良好特性的黄白色发光二极管（led）。
Two newly synthesized ultra-small copper nanoclusters, [Cu-3(mu(3)-H) (mu(2)-dppy)(4)](ClO4)(2) (1) and [Cu-4(mu(4)-H)(mu(2)-dppy)(4)(mu(2)-Cl)(2)](ClO4) (2) (dppy = diphenyl-2-pyridylphosphine), have been shown to exhibit ultrabright yellow and yellow-green room-temperature phosphorescence (RTP) emission, with high quantum yields of 71.8% and 63.5%, respectively. Therefore, nanocluster 1 has been applied for the first time as a single component phosphor for yellow and white light-emitting diodes (LEDs) with favourable characteristics.
