摘　　要：采用美国德州仪器公司开发的Spreeta系列小型化SPR传感模块,实验研究了环境温度变化对便携式表面等离子体共振传感器工作特性的影响.发现随着温度的升高,共振角度向小角度方向移动,并提出了完整的理论分析模型.该模型讨论了环境温度变化对金属薄膜、棱镜、待测物的物理性质的影响,模拟结果与实验测量结果吻合得很好.In actual application, the performance of surface plasmon resonance （SPR） sensors is influenced by the varying temperature of the environment. The temperature characteristic of portable SPR sensors is experimentally studied by use of Spreeta SPR sensing module, which is developed by Texas Instrument Incorporation. It is found that the resonant angle shift to small value with the increase of the temperature. A detailed theoretical model is provided to analyze the variation of performance with varying temperature of the sensing environment. The temperature dependence of the properties of the metal film, prism and analyte are all considered. The numerical results indicate that the predictions of the theoretical model are well consistent with the experiment data.
