From the Beginning, the Synthetic Strategies of the Perovskite Quantum Dots with High Quality |
| 초록 |
Obtaining independent synthetic method for key materials of perovskite quantum dot for next-generation energy industry, are required to be localized due to Japanese export regulations. Perovskite quantum dots formed CsPbI3-structure using synthesized and purified precursor, PbI2. This study seeks to find correlation of the main material’s purity and the effect of perovskite quantum dot by making up a way for the main materials of the perovskite quantum dot. Quantitative analysis about the quantum dot were performed through tunneling electron microscope, X-ray diffractometer, scanning electron microscope, UV-visible absorption spectrophotometer, photoluminescence spectrophotometer, and so on. Photoluminescence quantum yield and stability measurements were able to inform that the correlation between purity of the materials and the performance of quantum dots. As a result, as the materials were refined, the performance of the quantum dots were improved. |
