Abstract

Perovskite quantum dots (PeQDs) have been regarded as an alternative to traditional phosphor color converters in the backlit display to improve the color gamut and rendition of LCD. However, the pending barriers of aggregation quenching and structure instability are hindering their practical applications. Herein, high-quality CsPbX3 (X = Br, Br/I) PeQDs were in situ precipitated inside glass to produce nanocomposites with superior optical performance and stability. The highest photoluminescence quantum yield (PLQY) of ∼100% for CsPbBr3@glass is ascribed to the elimination of the inner filter effect via a physical dilution approach to restore its apparent value to an intrinsic one, and the exceptional photostability and water/heat resistance are benefited from their effective isolation from the external environment by the surrounding glass network units. Employing the PeQDs@glass@PDMS monolithic film, a high-performance backlit LCD was designed, and its color gamut reached 152% of commercial LCD and 103% of NTSC, demonstrating a great potential in the optoelectronic industry.
