摘要：

Yb3+-Er3+ co-doped all inorganic cesium lead bromide perovskite nanocrystals were prepared by hot injection method. The photoluminescence properties and crystal structure were characterized by transmission electron microscopic，fluorescence spectrum and X-ray diffraction. The experimental results show that Yb3+-Er3+ co-doped all inorganic perovskite nanocrystals emit bright green light（540 nm）and red light（646 nm）under the excitation of near-infrared light. In addition，it was found in the experimental process that the morphologies tuning of the Yb3+-Er3+ co-doped perovskite bromide nanostructures i. e. quantum dots，nanotubes，nanorods，nanoflowers，nanobelts，nanosheets have been successfully achieved by controlling reaction temperature，the temperature injected by the precursor and the proportion of the complexing agent and solvent. For Yb3+-Er3+ co-doped perovskite nanocrystals with different morphology，the phenomenon of Yb3+ sensitization Er3+ luminescence was observed under the excitation of near-infrared light，which is due to the existence of Yb3+-Er3+ energy transfer. Rare earth doping of perovskite materials can realize the up-conversion luminescence phenomenon under the excitation of near-infrared light，which is beneficial to the application of perovskite family materials in biomedical field. © 2024 Editorial Office of Chinese Optics.
