Gold nanoparticle clusters and/or chains, prepared and coated by solution processes, are introduced to improve optical absorption in Mn_1.56Co_0.96Ni_0.48O₄ (MCNO) films for the first time. Based on such a strategy, the response of the proposed film bolometer increases by 7.4% in the infrared region and 13.5% at the millimeter-wave frequency of 25.4GHz, respectively. It means that we find an effective method of achieving broadband enhancements in the film bolometer using plasmonic effects. Our approach is convenient and efficient not only for MCNO film bolometer but also for other thermal detectors.
