Abstract

Herein, we report UV-pumped white light emissive carbon dot (CD)-based phosphors to prevent blue light hazard in phosphor-converted WLEDs. Then, UV-pumped WLEDs with a color rendering index exceeding 85 and VLC with a modulation bandwidth of 75 MHz and a data transmission rate of 224 Mbps have been realized.
