Direct lithography of CsPbCl 3 , CsPbBr x Cl 3-x and CsCd x Pb 1-x Br 3 perovskite nanocrystals in organic media

The in-situ generation of perovskite nanocrystals within organic media using a femtosecond laser can greatly simplify the sample preparation process and save pulse energy. In this work, three perovskite nanocrystals (PNCs), CsPbCl , CsPbBr Cl , and CsCdxPb Br , were generated in situ within organic...

description The in-situ generation of perovskite nanocrystals within organic media using a femtosecond laser can greatly simplify the sample preparation process and save pulse energy. In this work, three perovskite nanocrystals (PNCs), CsPbCl , CsPbBr Cl , and CsCdxPb Br , were generated in situ within organic media using a femtosecond laser. These three perovskite nanocrystals emitted pure blue or blue-green fluorescence under ultraviolet (UV) irradiation. It was also found that by controlling the laser pulse energy, the CsCd Pb Br nanocrystals transitioned from green to blue-green fluorescence. Furthermore, we have successfully realized the patterning of these three perovskite nanocrystals in organic media.
