摘要

结合局部表面等离子体激元极化增强荧光的设备具有比传统对应物更敏感、更有效和更小的潜力。本文将描述一项独特的研究，研究Tb3+掺杂的多钽酸钇Tb0.15Y0.85Ta7O19在1000- 5000nm区域的荧光增强。溅射到等离子体金纳米颗粒薄膜上后，与厚度相关的红外荧光增强因子是相同厚度无金颗粒薄膜的0.64-6倍。t0.15 y0.85 ta7o19薄膜厚度对荧光增强因子的依赖关系将在电磁理论的背景下进行描述。

Near-and mid-infrared fluorescence enhancement in terbium-yttrium polytantalate

Devices incorporating localized surface plasmon polariton-enhanced fluorescence have the potential to be more sensitive, effective and smaller than their traditional counterparts. A unique study examining the fluorescence enhancement of Tb3+ doped yttrium polytantalate, Tb_0.15Y_0.85Ta₇O₁₉, in the 1000-5000 nm region will be described. After sputtering onto films of plasmonic gold nanoparticles, thickness dependent, infrared fluorescence enhancement factors were found to be 0.64-6-fold relative to the same thickness film without gold particles. The large Tb_0.15Y_0.85Ta₇O₁₉ film thickness dependence on the fluorescence enhancement factor will be described within the context of electromagnetic theory.
