Abstract: While quasi‐two‐dimensional (quasi‐2D) perovskites have emerged as promising semiconductors for light‐emitting diodes (LEDs), the broad‐width distribution of quantum wells hinders their efficient energy transfer and electroluminescence performance in blue emission. In particular, the underlying mechanism… read more here.
