A novel La2Mg1.14Zr0.86O6:Bi(3+)double perovskite phosphor with excitation-induced blue/green photoluminescence tuning is reported. By designing Bi3+-> Eu(3+)energy transfer, single-composition white light with wide-scale adjustable corrected color temperatures (CCTs) is successfully achieved. This work initiates a new insight to explore phosphors with excitation-induced photoluminescence tuning and wide CCT control for future intelligent LED lighting.
