摘要
Lead-free double perovskites have become the research hotspot in the optoelectronic fields. Then, it is a challenge to utilize the lattice doping by different rare earth ions with rich energy level and unique luminescence for emerging photonic applications. Here, we successfully prepared Sb3+ and Ln3+ ions doped Cs2NaYCl6 single crystals (SCs), bringing tunable bright luminescent emissions of blue, red, and white light, the highest photoluminescence quantum yield (PLQY) is up to 58.33%. Based on excellent and tunable luminescent properties, the multicolor light-emitting diodes (LEDs) applications for the rare earth-based double perovskite SCs were designed. These findings indicate that rare earth-based double perovskite will provide a broader application space for lighting.
