Herein, we present a two-step method to dope various amounts of Yb into CsPbBr1.5Cl1.5 QDs at room temperature. It is found that the CsPbBr1.5Cl1.5 QDs can exhibit strong similar to 990 nm near-infrared (NIR light) emission, and the NIR photoluminescence quantum yield (PLQY) is able to reach similar to 90% when 10% Yb is doped in the CsPbBr1.5Cl1.5 QDs.
