Abstract: In situ temperature measurement for closed systems is always challenging due to various physical limitations. With the aim to visualize the heat transfer phenomena in situ continuously with a longer time scale, octylamine substituted CsPbBr3 perovskite quantum dots (QDs) are synthesized, leading to its thermo-sensitity being doubled. An optical-based 2D temperature sensor based on these ligand-modified QDs is developed, targeting microreactors and other circumstances where conventional thermal sensing protocols are not applicable. The developed method has the advantages of repeatability, long lifetime, low cost, fast response time, and broader applicability since it does not require IR transparent substrates. On top of these advantages, the proposed method also provides satisfactory spatial and temporal resolution, which is typically limited by the camera’s specification rather than the materials.
