Anion Exchange in Yb-Doped All-Inorganic Perovskite NCs

Perovskite nanocrystals have demonstrated an excellent possibility of tuning their optical properties in the visible and near-infrared ranges (NIR). At present, Yb-doped perovskites CsPbCl

are popular optical nanomaterials for the development of the next-generation electronic devices due to the sharp electronic transition of ytterbium in the NIR. Here, we have developed anion exchange procedures with usage of different chemical compounds and studied optical properties in visible and near-infrared ranges of obtained nanocrystals.
