Abstract The luminescence from lanthanide ions has potential applications in light emitting diodes, biomedical, solar cells, sensors, display, etc. However, the luminescence is suffered from the various problems, such as low luminescence efficiency and inharmonious wavelength for energy transfer. Magnetic field is an efficient method to modulate the wavelength and intensity of luminescence from lanthanide ions. Magnetic field redistributes the populated electrons in the excited states to tune the wavelength of lanthanide ions by Zeeman effect, mixing effect, and quantum confinement effect. Magnetic field enhances or suppresses the luminescence intensity by the administration of cross-relaxation, energy transfer, and Boltzmann population. In this review, we first introduce the various phenomena and mechanisms of magnetic field modulated downshift luminescence from lanthanide ions, including Zeeman effect, cross-relaxation, crystal structure, absorption, quantum confinement effect, and magnetic–optical hysteresis. Then, we explain the regulation of upconversion luminescence by magnetic field, containing energy transfer and mixing effect. Finally, different options regarding how to understand the mechanism of magnetic field-modulated luminescence from lanthanide ions in the future are outlined. Graphic abstract

无机晶体中镧系离子的磁场调制发光机制:综述

摘要 镧系离子发光在发光二极管、生物医学、太阳能电池、传感器、显示器等方面具有潜在的应用前景,但其发光存在发光效率低、能量传递波长不协调等诸多问题。磁场是调制镧系离子发光波长和强度的有效方法。磁场重新分布处于激发态的电子,通过塞曼效应、混合效应和量子限制效应来调整镧系元素离子的波长。磁场通过交叉松弛、能量转移和玻尔兹曼布居来增强或抑制发光强度。在这次审查中,我们首先介绍了来自镧系离子的磁场调制下移发光的各种现象和机制,包括塞曼效应、交叉弛豫、晶体结构、吸收、量子限制效应和磁光滞后。然后,我们解释了磁场对上转换发光的调节,包括能量转移和混合效应。最后,概述了未来如何理解镧系元素离子的磁场调制发光机制的不同选择。图形摘要 最后,概述了未来如何理解镧系元素离子的磁场调制发光机制的不同选择。图形摘要 最后,概述了未来如何理解镧系元素离子的磁场调制发光机制的不同选择。图形摘要
