Progress in the Development of Heavy Metal-Free Quantum Dots for Electroluminescent Displays

The colour purity and high photoluminescence quantum efficiency of quantum dots has led to their widespread use in the backlight units of liquid crystal displays. However, as industry standards continue to push the boundaries of display technology, new technologies are needed to meet these requirements. Herein, we discuss the development of heavy metal-free quantum dots for use in next-generation electroluminescent displays.
