Abstract The study on phosphors‐converted white light‐emitting diodes (pc‐WLEDs) using lead‐free double perovskites (DPs) as single‐component phosphors is widely concerned. However, the photoluminescence quantum yields (PLQY) of luminescence and color rendering index (CRI) WLED are not satisfactory. Herein, a new Sb/Ho: Cs 2 Na 0.9 Ag 0.1 (In/Bi)Cl 6 phosphor with highest PLQY 93% record CRI 97.4 reported. Experimental data theoretical calculations evidence that in addition to broadband yellow emission self‐trapped exciton (STE) recombination, material also exhibits blue from Sb 3+ : 3 P 1 → S 0 transition red one assigned Ho 5 F I 8 transition. Steady‐state time‐resolved PL spectra verify existence two energy transfer channels both STE dopants. As demo, (In/Bi) Cl6‐based constructed, showing excellent comprehensive optical performance specially improved saturation R9 R12. This work provides novel rare‐earth doped DP for high full‐spectrum solid‐state lighting.

In contemporary society, lighting has become indispensable in both daily life and industrial activities. Researchers are actively developing new materials technologies to meet global goals for clean, sustainable energy. Among them, halide perovskite play a vital role light-emitting diodes (LEDs) due their high carrier mobility, low exciton binding energy, tunable emission wavelength. White (WPeLEDs) based on single layer (SEL) feature simpler production processes clearer luminescence mechanisms compared with other layered series devices, attracting extensive research interest showing great potential practical applications. This Account systematically provides an overview of the recent advances SEL-WPeLEDs. The concepts luminescent principles PeLEDs first elaborated, typical approaches film deposition then summarized. Subsequently, implementation strategies toward high-performance SEL-WPeLEDs electric driving, including Perovskite Self-trapped excitons, perovskite-organic molecule coupling, metal ion doping, carefully discussed. Finally, challenges perspectives further development SEL-PeLEDs proposed.
