摘要：

White-light emitting materials (WLEMs), especially single-component WLEMs, have always been a research hotspot for their great application potential in white-light emitting diodes (WLEDs). However, the white-light performance of WLEMs, including the quantum yield, color rendering index and so on, has not been greatly improved. The organic-inorganic hybrid perovskites (OIHPs) emerging in recent years have brought vitality to the development of WLEMs and WLEDs because of their excellent white-light emission characteristics. By adjusting the types and proportions of metal cations, halogen anions and organic components, the band gap width and Stokes shift of OIHPs can be adjusted effectively, thus realizing a wide emission covering the whole visible region. In this review, the structure, photophysical properties, and white-light mechanism of OIHPs with white emission are summarized, emphasizing white-light performance adjustment strategies. The further research directions and challenges of white-light emitting OIHPs are proposed to develop high-performance WLEMs meeting various application requirements in the future.
