Abstract: 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.
