Quantum dot light-emitting diodes (QLEDs) have been considered as potential display technologies with features such as high color purity, flexibility, transparency, and cost efficiency. For practical applications, the development of Cd-free QLEDs from environment-friendly materials is the most important issue to reduce the impacts on human health and environmental pollution. In this work, we report the fabrication of QLEDs based on high color purity InP-based QLEDs. The InP-based QLEDs showed a turn-on voltage of ~2.6 V, a maximum luminance of ~1200 cd/m2 and a current efficiency of 0.55 cd/A. The EL emission wavelengths was ~538 nm with full width at half maximum (FWHM) of 41 nm, respectively. The EL FWHM value is much excellence than the other InP-based QLEDs reported previously. Overall, the InP-based QLEDs exhibit the potential to be the technology for future display applications. |
