recommendations! Published in 2025 at "ACS applied materials & interfaces"

DOI: 10.1021/acsami.5c12517

Abstract: Luminescent solar concentrators (LSCs) based on high photoluminescence quantum yield (PLQY) quasi-2D perovskites demonstrate superior edge light collection capability, which breaks the étendue limit and achieves signal reception in visible light communication (VLC). Herein, 2,7-bis(diphenylphosphoryl)-9,9-spirobifluorene… read more here.

DOI: 10.1080/00207217.2017.1296594

Abstract: ABSTRACT In this paper, we propose an inter-lighting interference cancellation (ILIC) scheme to reduce the interference between adjacent light-emitting diodes (LEDs) and enhance the transmission capacity of multiple-input–single-output (MISO)-visible light communication (VLC) systems. In indoor… read more here.
