Abstract
The cover features space as a backdrop, in which carbonized polymer dots (CPDs) particles are likened to the composition of planetary ring. The solid‐state fluorescence intensity of the CPDs varies with the degree of particles’ aggregation, exhibiting the property of aggregation‐induced emission. In this work, CPDs with aggregation induced solid‐state fluorescence emission were successfully designed and synthesized. Based on the structural characterization and spectrum data, the formation process and aggregation‐state fluorescence mechanism of polythiophene‐derived CPDs were postulated. Owing to their unique properties of solid‐state fluorescence, the CPDs‐phosphor‐based white LEDs with CRI of 82.7 and CIE coordinates of (0.37, 0.39) using commercial 460 nm chip were achieved. This work elucidates the solid‐state fluorescence mechanism of such polythiophene‐derived CPDs, and displays the potential application of such CPDs in the field of optoelectronic devices. More details are discussed in the article by Ge et al. on page 1950—1956.image
