When it comes to photonic optoelectronic materials, colloidal nanocrystals of semiconductor quantum dots (QDs) are quickly rising to the top of the heap. With their great efficiency and narrow emission band, they have gained interest for their usage in artificial lighting and displays because of their spectral purity and fine-tunability. As a result of using QDs in color-conversion LEDs in combination with phosphors, it is possible to simultaneously achieve successful color rendition of illuminated objects. The device spectral overlap with the sensitivity of the human eye is outstanding, in contrast to other conventional sources like incandescent and fluorescent lights and phosphor-based LEDs, which cannot attain all of the above features at the same time. Color science of QDs for lighting and displays is summarized in this paper, along with recent breakthroughs in QD-integrated LEDs and display research. Color science, photometry, and radiometry are introduced in the first chapter. Spectral designs of QD-integrated white LEDs have resulted in efficient lighting for both indoor and outdoor applications after offering an overview of QDs. QD color-conversion LEDs and displays are discussed as proof-of-concept applications in the next section. Finally, we present an overview of research opportunities and difficulties, as well as a prediction for the future. |
