Pressure-induced white-light emission of a Cu() cluster with effective blue phosphorescence

Single-component white-light emitters have attracted increasing attention due to their advantages of convenient fabrication and energy conservation. However, blue phosphorescent materials are not easily obtained. Here, we develop a new strategy to realize white light emission in a Cu( i ) cluster (...

Description
Summary:Single-component white-light emitters have attracted increasing attention due to their advantages of convenient fabrication and energy conservation. However, blue phosphorescent materials are not easily obtained. Here, we develop a new strategy to realize white light emission in a Cu( i ) cluster ( 1 ). 1 displays effective blue phosphorescence with a photoluminescence quantum yield ( ) of 68.5%, attributed to the good dispersion of the phosphor centres. A new yellow emission peak at 580 nm is observed after grinding, which combines with the blue phosphorescence to form white light emission ( = 17.29%) with the CIE coordinates of (0.34, 0.36). A white light-emitting diode (WLED) is fabricated as well, which shows high performance with a satisfactory colour rendering index of 81.5 and correlated colour temperature of 6856 K. 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.
