Perovskite CsPbBr<sub>3</sub> Quantum Dots Prepared Using Discarded Lead–Acid Battery Recycled Waste

Perovskite CsPbBr<sub>3</sub> Quantum Dots Prepared Using Discarded Lead–Acid Battery Recycled Waste

Perovskite CsPbBr<sub>3</sub> quantum dot (CsPbBr<sub>3</sub>-QD) recovery was performed using lead scrap from lead storage batteries. The perovskite CsPbBr<sub>3</sub>-QD characteristics were analyzed using different PbO/recycled PbO<sub>2</sub> ratio...
