Abstract

Breaking the NIR-II bottleneck, conventional inorganic semiconductors have long suffered from inadequate optical absorption, limiting their phototherapeutic efficacy. Here, we report a paradigm-shifting breakthrough: the first-ever hydrothermal synthesis of high-entropy (FeCuMn)(WMo)O_4₋xS_x nanosheets. By overcoming the fundamental immiscibility of five transition metals, our monoclinic nanosheets unlock an unprecedented broadband absorption spanning 400–1400 nm, achieving record-high photothermal conversion in both the NIR-I and NIR-II biological windows (ΔT = 38 °C at 808 nm). Remarkably, this high-entropy configuration simultaneously endows the material with strong T₁/T₂ magnetic relaxivity, enabling novel dual-modal MR imaging capability. This first demonstration of integrating photothermal and magnetic functionalities via hydrothermal high-entropy engineering opens a new avenue for theranostic nanoplatforms.

水热法合成高熵（FeCuMn）（WMo）O4-xSx纳米片的形成机理及光学/磁性能

突破NIR-II瓶颈，传统无机半导体长期遭受光吸收不足的困扰，限制了其光疗效果。在这里，我们报告了一个范式转换的突破：首次水热合成高熵（FeCuMn）（WMo）O4纳米片。通过克服五种过渡金属的基本不混溶性，我们的单斜纳米片开启了跨越400-1400 nm的前所未有的宽带吸收，在NIR-I和NIR-II生物窗口（ΔT = 38°C at 808 nm）中实现了创纪录的高光热转换。值得注意的是，这种高熵结构同时赋予材料强T1/T2磁弛豫度，实现了新的双峰磁共振成像能力。这是通过水热高熵工程整合光热和磁功能的首次演示，为治疗性纳米平台开辟了新的途径。

期刊介绍： The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
