Abstract

Photon avalanche (PA) upconversion in lanthanide nanosystems represents a groundbreaking discovery, demonstrating an optical nonlinearity exceeding 50. This remarkable sensitivity to even the slightest light perturbations unlocks new possibilities for ultrasensitive biosensing, super-resolution imaging, and a range of other applications. This review delves into the fundamental mechanisms underlying PA and the approaches for controlling energy flow within these nanomaterials. We present innovative design strategies for optimizing optical dynamics tailored to specific applications. Furthermore, we critically assess the advantages and limitations of PA technology across diverse applications. In addition, we explore future directions, highlighting the key challenges and proposing pathways for further research. By enhancing the understanding of PA phenomena and encouraging interdisciplinary collaboration, this review seeks to foster ongoing innovation at the convergence of nanophotonics and materials science, pushing the boundaries of current capabilities in photonics research.

镧系元素光子雪崩纳米光子学的新进展

光子雪崩（PA）在镧系纳米系统中的上转换代表了一个突破性的发现，证明了光学非线性超过50。即使是最轻微的光扰动，这种非凡的灵敏度也为超灵敏生物传感、超分辨率成像和一系列其他应用打开了新的可能性。这篇综述深入探讨了PA的基本机制和控制这些纳米材料内能量流动的方法。我们提出了创新的设计策略，以优化特定应用的光学动力学。此外，我们批判性地评估了PA技术在不同应用中的优势和局限性。此外，我们还探讨了未来的方向，强调了关键挑战并提出了进一步研究的途径。通过加强对PA现象的理解和鼓励跨学科合作，本综述旨在促进纳米光子学和材料科学融合的持续创新，推动当前光子学研究能力的界限。
