Fluorescent Red-Emitting BODIPY Oligofl uorene Star-Shaped Molecules as a Color Converter Material for Visible Light Communications
The ever growing demand for wireless data communications is driving a need for new technologies to augment the
existing radio frequency approaches (such as WiFi). Visible light communications (VLC) offers a means to do this, using
the unlicensed visible region of the electromagnetic spectrum for wireless communications, where hundreds of terahertz of bandwidth are available. The adoption of light-emitting diode (LED) lighting makes this possible, as standard lighting fi xtures can be used for both illumination and data communications.[ 1–3 ] Data are encoded by modulating the light source, and the rate of data transmission that can be achieved depends on the modulation bandwidth of the LED and its phosphor coating.In addition, it must emit suffi cient optical power to create the required signal-to-noise ratio at the receiver for the particular modulation format used.
