Enables Large-Scale Production of Precision Quantum Dots for Medical Imaging, LEDs and Solar Cells
This multi-variable reactor facilitates the manufacturing of high-precision, core-shell quantum dots – nanoparticles made from semiconductive materials that display unique optical and electrical properties. Quantum dots have applications in computing, photovoltaic devices (solar panels), light emitting diodes (LEDs) and medical imaging equipment.
By modifying or “tuning” the precise size and quality of quantum dots, scientists can control the wavelength (bandgap) of light emitted by LEDs, and can select the properties for various other applications, such as fluorescence-based diagnostics and cell staining in medical imaging. Quantum dots are currently manufactured using batch methods, which under hydrothermal conditions, are time-consuming and subject to batch-to-batch variation in the desired properties. Detailed tuning of quantum dots to precise optical properties can be difficult using existing technology. Researchers at the University of Florida have developed a hydrothermal reactor that offers high-precision tuning of quantum dots for bulk production. The reactor enhances reliability, precision, uniformity and throughput during large-scale quantum dot manufacturing, and could help capture a significant portion of the global quantum dots market, which is expected to reach $670 million by 2015.
