Blue Superluminescent Diodes with GHz Bandwidth Exciting Perovskite Nanocrystals for High CRI White Lighting and High-Speed VLC

Not Accessible

Your library or personal account may give you access


A 442-nm GaN-based superluminescent diode (SLD) is demonstrated with a GHz modulation bandwidth and a linewidth of 7 nm. When use for exciting CsPbBr3-perovskite nanocrystal-phosphor, warm-white light with a high CRI of 91 was achieved.
