Temperature characteristics of near infrared SPR sensors with Kretschmann configuration

Abstract

The temperature characteristics of near infrared surface plasmon resonance (SPR) sensors with Kretschmann configuration are studied theoretically and experimentally. The experimental results match with the numerical simulations in the temperature range from 10 °C to 40 °C. With the increase of temperature, the resonance angle for gas increases slightly, but that for aqueous solution decreases obviously. No matter the dielectric layer is gas or aqueous solution, the resonance peaks are both broadened.
