摘要
Lead halide perovskite quantum dots (PQDs) have attracted plenty of attention in light-emitting diodes (LEDs) applications owing to their tunable bandgap, narrow bandwidth, high photoluminescence quantum yields (PL QYs), and facile fabrication. Despite applying PQDs in LEDs has found huge success, the poor stability greatly hampered their commercialization. The irreversible degradation driven by light, heat and open air leads to severely PL quenching, and then decreasing the electro-optical conversion efficiency of devices. The poor stability has attracted intense attention. Within a few years, a lot of interesting results have been published, and the reported stability of PQDs was greatly enhanced. This review describes some of the recent advances made in this area, and their applications in LED are summarized.
