Industry outlook of perovskite quantum dots for display applications

Nature Nanotechnology volume 17, pages 813–816 (2022)Cite this article

Subjects

Perovskite quantum dots have been proven promising for photonic and optoelectronic applications, particularly, as bright and narrow band emitters for display technology. Despite the advantageous properties, the stability issues have to be resolved to unleash the full industrial potential of perovskite quantum dots in display technology.
