Abstract

Sensors utilizing magneto-optical surface plasmon resonance are gaining increasing scientific and practical attention to detect atmospheric gases and humidity. The magneto-optic surface plasmon resonance wavelength is defined by the plasmonic structure's geometry and structure, making it immune to electromagnetic interference outside its resonance frequency range. The present study investigates their application for the detection of atmospheric gases including humidity. In contrast to conventional sensors, magneto-optic sensors exhibited excellent performance in terms of sensitivity (10 times greater), higher quality factor (up to 76 times higher) and design simplicity in terms of layer thickness optimization, integration, and robustness. These results suggest significant potential for utilization of magneto-optic sensors across multiple industries.

兼具质子和磁性活性的传感器

利用磁光表面等离子体共振检测大气中的气体和湿度的传感器正受到越来越多的科学和实际关注。磁光表面等离子体共振的波长由等离子体结构的几何形状和结构确定，使其不受共振频率范围以外的电磁干扰。本研究探讨了其在检测包括湿度在内的大气气体方面的应用。与传统传感器相比，磁光传感器在灵敏度（高 10 倍）、更高的品质因数（高达 76 倍）以及在层厚度优化、集成和稳健性方面的设计简易性等方面表现出卓越的性能。这些结果表明，磁光传感器在多个行业的应用潜力巨大。
