Transition metal dichalcogenides, including WSe 2 , have gained significant attention as promising nanomaterials for various applications due to their unique properties. In this study, we explore the temperature-dependent photoluminescent properties of WSe 2 nanomaterials to investigate their potential as luminescent nanothermometers. We compare the performance of WSe 2 quantum dots and nanorods synthesized using sonication synthesis and hot injection methods. Our results show a distinct temperature dependence of the photoluminescence, and conventional ratiometric luminescence thermometry demonstrates comparable relative thermal sensitivity (0.68-0.80% K -1 ) and temperature uncertainty (1.3-1.5 K), irrespective of the morphology of the nanomaterials. By applying multiple linear regression to WSe 2 quantum dots, we achieve enhanced thermal sensitivity (30% K -1 ) and reduced temperature uncertainty (0.1 K), highlighting the potential of WSe 2 as a versatile nanothermometer for microfluidics, nanofluidics, and biomedical assays. |
