CsPbBr(3)/CdS Core/Shell Structure Quantum Dots for Inverted Light-Emitting Diodes Application

Novel CsPbBr(3)/CdS core/shell structure quantum dots (QDs) were successfully synthesized using a facile hot-injection method. The corresponding CsPbBr(3)/CdS QDs based light-emitting diodes (QLEDs) were further prepared, which demonstrated the maximum luminance of 354 cd/m(2) and an external quantu...

description Novel CsPbBr(3)/CdS core/shell structure quantum dots (QDs) were successfully synthesized using a facile hot-injection method. The corresponding CsPbBr(3)/CdS QDs based light-emitting diodes (QLEDs) were further prepared, which demonstrated the maximum luminance of 354 cd/m(2) and an external quantum efficiency (EQE) of 0.4% with the current efficiency (CE) of 0.3 cd/A. Moreover, the optoelectronic performance of the CsPbBr(3)/CdS QDs based QLEDs exhibited a comparable enhancement in contrast to the pure CsPbBr(3) QDs based QLEDs. Hypothetically, the novel CsPbBr(3)/CdS structure QDs introduced one new route for advanced light emission applications of perovskite materials.
