Focus on perovskite emitters in blue light-emitting diodes
In recent years, the advancement of LEDs based on perovskite materials has progressed significantly. The benefits of perovskite materials, including their straightforward production processes, wide color gamut, high color purity, and low cost, have facilitated the development of efficient red and green PeLED devices, which currently surpass 25% in efficiency. Consequently, PeLEDs have become one
