| titleOfInvention | A centimeter-length perovskite single crystal fiber and its preparation method and application |
| abstract | The invention belongs to the field of single crystal growth, and discloses a centimeter-length perovskite single crystal fiber and a preparation method and application thereof. The preparation method includes: sucking the perovskite precursor solution through capillary force or injecting it into the hollow fiber channel by external force; drying the fiber channel in a vacuum drying oven. The preparation process of the invention is simple, and the liquid perovskite precursor gain medium can be inhaled by capillary force or injected by external force to obtain high-quality bromine-based perovskite single crystals without macroscopic and microscopic defects (that is, colorless, transparent, and good integrity. , single crystal that is not easy to crack), and the single crystal is closely attached to the quartz template, the quartz template isolates the air and moisture in the external environment, and improves the crystal storage performance. Under laser excitation, the obtained perovskite single crystal in the tube emits strong green light and exhibits obvious ASE characteristics, which has the potential to realize laser emission. |
