Halide perovskite quantum dots: potential candidates for display technology

Research Highlight

Motivated by the color tunability and narrow-band emission peak of colloidal quantum dots (QDs), the concepts of quantum dot light-emitting diodes (QD-LEDs), based on either the photoluminescence (PL) or electroluminescence (EL) mechanism, have been proposed for a few years [1]. Using QD-LEDs in the backlighting system of liquid crystal display (LCD) can significantly expand the color gamut of display and present vibrant colored images. However, even though CdSe-based QDs have been commercially used in backlighting system, this innovative technique is still suffering from the complicated preparation process, the lack of surface control during process, and unacceptable price of high-quality CdSe-based QDs. Moreover, the developing of high-performance (bright, efficient, and stable) EL devices strongly relies on the precise band engineering of the core and shell as well as surface ligands [2]. To solve these problems, alternative materials with simple process have been much aspired.
