| 本实验将能量转移概念引入大学化学实验教学中，提高学生的创新意识和创新能力。采用发光亮度高、波长可调的钙钛矿量子点作为能量给体，具有光致变色能力的螺噁嗪类分子作为能量受体，构建能量转移体系。通过探究不同发光波长的量子点材料与光致变色分子间的能量转移过程，使学生进一步深刻认识能量转移及光致变色分子变色机理，并探索复合体系在光学防伪领域的潜在应用。钙钛矿量子点—分子复合体系的制备简单，光致变色后能量转移效果明显，可作为大学本科综合化学实验。本实验旨在使学生系统性掌握能量转移、钙钛矿量子点材料和光致变色等相关科技前沿领域的基础知识，提高本科生的科研兴趣和综合创新能力。 |
| 英文摘要: |
| The energy transfer process of the quantum dot-molecule composite system has significant application value in improving the optical performance of optoelectronic devices. In this experiment, perovskite quantum dots with high luminescence brightness and tunable wavelengths are used as energy donors, and spiropyran-based molecules with photochromic properties are used as energy acceptors to construct an energy transfer system. By exploring the energy transfer process between quantum dot materials with different emission wavelengths and photochromic molecules, students can further deepen their understanding of energy transfer and the color-changing mechanism of photochromic molecules, and explore the potential applications of the composite system in the field of optical anti-counterfeiting. The preparation of the perovskite quantum dot-molecule composite system is simple, and the energy transfer effect is obvious after photochromism, making it suitable as a comprehensive chemistry experiment for undergraduate students. It is hoped that through this experiment, students can systematically master the basic knowledge of energy transfer, perovskite quantum dot materials, and photochromism and other cutting-edge fields. |
