Description
https://arxiv.org/abs/2510.25667
Quantum dots (QDs) are nanoscale semiconductor materials whose optical and electronic properties can be precisely tailored through composition, size, and surface engineering. Their unique characteristics—including tunable emission wavelengths, high photoluminescence efficiency, large absorption cross-sections, excellent radiation sensitivity, and compatibility with diverse host materials—have positioned them as promising functional materials for next-generation technologies across multiple disciplines.
This talk will provide an overview of recent advances in quantum dot research and explore their emerging applications in high-energy physics, space science, and medicine.
In high-energy physics, quantum dots offer novel opportunities for scintillation detectors, wavelength-shifting materials, particle tracking, radiation sensing, quantum sensing, and rare-event searches, including dark matter and neutrino experiments. Their integration into detector media, optical fibers, and advanced photonic systems may enable enhanced light collection, improved timing resolution, and new approaches to particle detection.
For space applications, quantum dots present exciting possibilities for radiation dosimetry, lightweight photonic devices, infrared sensing, solar energy harvesting, and environmental monitoring in harsh extraterrestrial environments. Their tunable optical responses and potential radiation hardness make them attractive candidates for future space missions and satellite instrumentation.
In the medical domain, quantum dots have already demonstrated significant potential in bioimaging, diagnostics, drug delivery, photodynamic therapy, and biosensing. Their bright and stable luminescence enables highly sensitive detection of biological processes, while advances in non-toxic and biocompatible quantum dots are expanding their clinical relevance.
The talk will highlight recent developments in quantum dot materials, including perovskite, chalcogenide, and doped semiconductor nanocrystals, and discuss future opportunities at the interface of quantum technology, advanced sensing, and multidisciplinary research. Particular emphasis will be placed on how engineered quantum dots can serve as a common technological platform linking fundamental physics, space exploration, and biomedical innovation.
