研究目的
To develop a self-assembled nanotemplate-confined growth concept to prepare ultrathin CsPbBr3 nanowires for potential applications in blue light emitting diodes and other optoelectronic devices.
研究成果
The study successfully developed a method to prepare ultralong and ultrathin CsPbBr3 nanowires using a self-assembled template-confined growth concept during electrospinning. The nanowires showed strong blue light emission, indicating potential applications in blue LED devices and other optoelectronic fields.
研究不足
The study does not address the long-term stability of the CsPbBr3 nanowires under operational conditions in optoelectronic devices.
1：Experimental Design and Method Selection:
The study employed electrospinning using a DMF solution composed of PMMA, PbBr2, CsBr, and capping agents to prepare ultrathin CsPbBr3 nanowires.
2：Sample Selection and Data Sources:
The precursors (PbBr2, CsBr) were thoroughly mixed with PMMA in DMF.
3：List of Experimental Equipment and Materials:
A high voltage power supply (12 kV), syringe pump, stainless steel needle, and rotating stainless steel plate were used for electrospinning.
4：Experimental Procedures and Operational Workflow:
The DMF solution was electrospun into PMMA fibers, which were then collected on a rotating plate. The PMMA fibers were dissolved in toluene to release the CsPbBr3 nanowires.
5：Data Analysis Methods:
The microstructure was characterized with an X-ray diffractometer, UV–vis absorption spectrometer, photoluminescence spectrometer, field-emission scanning electron microscope, and transmission electron microscope.
