                     Timeline showing recent progress in fluorescent nanomaterial-derived white LEDs.


Abstract: White light-emitting diodes (white LEDs) have recently attracted substantial interest owing to their

remarkable energy conservation. The evolution of fluorescent nanomaterials with tunable optical

properties has provided an opportunity for light source design of white LEDs. However, the stability and

performance of fluorescent nanomaterial-derived white LEDs still fail to meet the requirements of

practical applications. It is therefore imperative to boost their overall device performance, which depends

on not only the exploitation of advanced fluorescent nanomaterials but also the design of superior light

source. In this review, the achievements in fluorescent nanomaterials as color converters towards white

LEDs are highlighted, including semiconductor nanocrystals or colloidal quantum dots (QDs), carbon-based

nanoparticles, silicon QDs, and organic-inorganic fluorescent nanocomposites. The challenges and

future perspectives in this research area are also discussed.
