Pressure-Induced White-Light Emission of a Cu(I) Cluster with Effective Blue Phosphorescence

Blue phosphorescence with the PLQY of 68.5% is achieved in a Cu( i ) cluster by dispersing the phosphor centres. And the ground sample show white-light emission and the CIE is (0.34, 0.36), which is further fabricated as the WLED with the R a of 81.5.
