摘要

Abstract

Warm WLED with high color rendering index (CRI) are greatly required for the widespread use of solid-state lighting especially indoors. Here

a remarkable improvement of CRI in alloyed CdS

0.7

0.3

QDs was achieved by pressure engineering. Notably

white light with enhanced CRI of 93

higher than pristine CRI of 47

was retained upon the complete release of pressure

accompanied by a color change from ‘natural’ (4298 K) to ‘warm’ white light (2170 K). Synchrotron ADXRD shows that CdS

0.7

0.3

QDs experienced an irreversible phase transition from the zinc blende phase to rocksalt structure.
