Summary
Lanthanide ions were doped into cesium lead halide perovskite nanocrystals, enabling stable, tunable multicolor emissions. This breakthrough enhances perovskite nanocrystal applications in optoelectronics.
Area of Science:
- Materials Science
- Nanotechnology
- Quantum Chemistry
Background:
- Cesium lead halide (CsPbX3) perovskite nanocrystals (NCs) exhibit excellent optical properties for optoelectronics.
- Achieving stable white-light and multicolor emission in CsPbX3 NCs is challenging due to anion exchange issues.
Purpose of the Study:
- To dope various lanthanide ions into CsPbCl3 perovskite NC lattices.
- To achieve stable, widely tunable multicolor emissions from visible to near-infrared (NIR) regions.
- To explore the inheritance of lanthanide ion optical properties by perovskite NCs.
Main Methods:
- A modified hot-injection method was employed for doping lanthanide ions (Ce3+, Sm3+, Eu3+, Tb3+, Dy3+, Er3+, Yb3+) into CsPbCl3 perovskite NCs.
- Photoluminescence quantum yield (QY) and emission spectra were characterized.
Main Results:
- Lanthanide ion-doped CsPbCl3 perovskite NCs were successfully synthesized.
- High photoluminescence quantum yield (QY) was achieved.
- Stable and widely tunable multicolor emissions from visible to NIR regions were obtained.
Conclusions:
- Lanthanide ion doping successfully imparts unique optical properties to CsPbCl3 perovskite NCs.
- The doped NCs exhibit enhanced optical characteristics, expanding their application potential.
- This approach offers a pathway to novel perovskite-based optoelectronic materials with tailored properties.
