White Light-Emitting Diodes Based on AgInS(2)/ZnS Quantum Dots with Improved Bandwidth in Visible Light Communication

Quantum dot white light-emitting diodes (QD-WLEDs) were fabricated from green- and red-emitting AgInS(2)/ZnS core/shell QDs coated on GaN LEDs. Their electroluminescence (EL) spectra were measured at different currents, ranging from 50 mA to 400 mA, and showed good color stability. The modulation ba...

description Quantum dot white light-emitting diodes (QD-WLEDs) were fabricated from green- and red-emitting AgInS(2)/ZnS core/shell QDs coated on GaN LEDs. Their electroluminescence (EL) spectra were measured at different currents, ranging from 50 mA to 400 mA, and showed good color stability. The modulation bandwidth of previously prepared QD-WLEDs was confirmed to be much wider than that of YAG:Ce phosphor-based WLEDs. These results indicate that the AgInS(2)/ZnS core/shell QDs are good color-converting materials for WLEDs and they are capable in visible light communication (VLC).
