Abstract
Quantumdot (QD) thermometry harnesses the sizedependent electronic structure of semiconductor nanocrystals to translate minute temperature variations into robust optical signals. In this work we present a systematic design framework for QDbased temperature sensors that integrates (i) bandgap engineering through precise colloidal synthesis, (ii) surfacestate passivation to suppress nonradiative pathways, and (iii) a planar photonicreadout architecture compatible with lowcost, CMOSfriendly fabrication. By exploiting the linear redshift of the photoluminescence (PL) peak (~0.3 nm K⁻¹ for CdSe/ZnS coreshells) and the concurrent increase in PL lifetime (≈2 % K⁻¹), we demonstrate a dualparameter readout capable of discriminating temperature changes as small as 0.1 °C over the biologically relevant range of 20–45 °C. A compact, fibercoupled excitation/detection module provides realtime monitoring with a latency below 10 ms, opening pathways to insitu metabolic mapping and rapid thermal management in microelectronics. The sensor’s performance is benchmarked against commercial thermocouples and infrared cameras, revealing a threeorderofmagnitude improvement in spatial resolution (subµm) while maintaining comparable accuracy (±0.08 °C). The paper concludes with an analysis of longterm photostability, temperatureinduced QD degradation, and strategies—such as alloyed cores and polymer encapsulation to mitigate drift. Collectively, the results establish QD technology as a versatile platform for nextgeneration temperature sensing, marrying nanoscale precision with scalable optics.
