Abstract

In 1891, Austrian scientist and entrepreneur Carl Auer von Welsbach filed a groundbreaking patent for a cotton mantle impregnated with cerium-doped thorium oxide, which converted the light and heat of gas lamps into a brilliant white glow. This marked the birth of lanthanide photonics and phosphor chemistry—a field that now underpins countless essential technologies, from solid-state lighting to cancer phototherapy and quantum computing information processing. This perspective explores the remarkable scientific journey of lanthanide photonics, highlighting recent breakthroughs and key developments. We begin with a historical overview before delving into fundamental advances including quantum chemical models, antenna effect and energy transfer mechanisms, the design of inorganic phosphors, the influence of electric and magnetic fields, molecular and circularly polarized luminescence, upconversion processes, and quantum bits. The final section focuses on cutting-edge applications, such as solid-state lighting, photovoltaics, mechanoluminescence, and biomedical innovations (optical imaging, cancer diagnosis, and photodynamic therapy), while briefly touching on other emerging uses. Rather than providing an exhaustive review, this article offers a concise yet broad overview of the field, spotlighting pivotal contributions from the past decade. Our goal is to capture the dynamism and interdisciplinary impact of lanthanide photonics as it continues to shape science and technology.
走向未来的镧系光子学:从气体照明到光学计算机
1891年,奥地利科学家和企业家卡尔·奥尔·冯·威尔斯巴赫申请了一项开创性的专利,他发明了一种浸有铈掺杂的氧化钍的棉罩,这种棉罩可以将煤气灯的光和热转化为明亮的白光。这标志着镧系光子学和荧光粉化学的诞生——这个领域现在支撑着无数的基本技术,从固态照明到癌症光疗和量子计算信息处理。这个视角探索了镧系元素光子学的非凡科学之旅,突出了最近的突破和关键发展。在深入研究包括量子化学模型、天线效应和能量传递机制、无机荧光粉的设计、电场和磁场的影响、分子和圆极化发光、上转换过程和量子比特在内的基本进展之前,我们从历史概述开始。最后一部分重点介绍了尖端应用,如固态照明、光伏、机械发光和生物医学创新(光学成像、癌症诊断和光动力治疗),同时简要介绍了其他新兴用途。本文不是提供详尽的回顾,而是对该领域进行了简明而广泛的概述,重点介绍了过去十年的关键贡献。我们的目标是捕捉镧系元素光子学的动态和跨学科影响,因为它继续塑造科学和技术。

期刊介绍: The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid. We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
