Inorganic halide perovskite quantum dot modified YAG-based white LEDs with superior performance

Inorganic perovskite CsPbBr_3−xI_x(x= 0–3) QDs with tunable emission wavelength, narrow emission band and high quantum yields were synthesized. The fabricated CsPbBrI₂QD-modified WLEDs show excellent performance in luminous efficacy, CCT and CRI, which are quite stable at an operational current as high as 350 mA.
