| description | Platinum (Pt) is a rare and precious metal element with numerous unique properties. These properties have led to the widespread use of Pt in electronic components, thermocouples, and high-temperature devices. In this study, we present the bolometric effect of single-metal Pt-based negative photoconductivity (NPC) devices under the laser irradiation of 375 nm, 532 nm, and 808 nm. Under the condition of applying 0.5 V voltage, the responsivity (<i>R</i>) of the Pt photothermal detector (Pt-PTD) under 375 nm laser irradiation was 69.14 mA/W, and the specific detectivity (<i>D*</i>) was 5.38 × 10<sup>7</sup> Jones; the <i>R</i> of the Pt-PTD under 532 nm laser irradiation was 59.46 mA/W, and the <i>D*</i> was 4.61 × 10<sup>7</sup> Jones; the <i>R</i> of the Pt-PTD under 808 nm laser irradiation was 37.88 mA/W, and the <i>D*</i> was 2.95 × 10<sup>7</sup> Jones. Additionally, a single-site scanning imaging system based on a Pt-PTD was designed to test the capability of the device. This study provides a strategy for the development of thermal measurement detectors based on Pt materials. |
