Abstract

We report that an ultrathin gold island film deposited on non-wetted substrates, such as silica, is effective for time-dependent ex-situ temperature sensing with a fast time response from 5 to 180 s. The sensing mechanism is based on morphological self-organization of the ultrathin gold films upon thermal-induced dewetting. The shift of the characteristic surface plasmon absorption band can behave as effective "fingerprint" for temperature recording and allows a rapid readout. Time-dependent dewetting behaviors of the ultrathin films (1.0-5.0 nm) and their effects on surface plasmon resonance were investigated, opening up the possibility for developing nano film-based temperature sensors with controllable sensitivities and fast response.
