White-Lighting Communication with $\text{Lu}_{3}\text{Al}_{5}\text{O}_{12}:\text{Ce}^{3+}/\text{CaAlSiN}_{3}:\text{Eu}^{2+}$ Glass Covered 450-nm InGaN Laser Diode

By using the Lu3Al5O12:Ce3+/CaAlSiN3:Eu2+ phosphor codoped fluorescent glass as a phosphor in front of an InGaN laser diode (LD), a novel white-lighting and visible light communication (VLC) module is demonstrated. By enlarging the fluorescent glass thickness from 0.7 to 1 mm, the CCT of the generated white light is increased from 7373 to 25000 K, and the maximal illuminance is enlarged from 1306 ...
