Perovskite materials are considered to be the ideal material for next-generation ultra-high resolution display technology, but pure red perovskite LEDs have long been plagued by the problem of low material stability.
A Chinese research team has overcome the challenges of pure red perovskite LED technology and successfully developed a pure red perovskite electroluminescent device (LED) that combines high efficiency and high stability. By in situ deposit, they stabilized ultrasmall CsPbI3 QD conductive solids, by constructing CsPbI3 QD/quasi–two-dimensional (quasi-2D) perovskite heteroepitaxy. Based on this “pure red”, it is expected that more detailed and colorful LED displays will be realized in the future.
