Method slashes quantum dot costs by 80 percent

... Quantum dots typically cost more than $2,000 per gram from commercial sources, and pricey solvents like octadecene, or ODE - the least expensive solvent used in quantum dot preparation today - account for about 90 percent costs of raw materials. Heat-transfer fluids - stable, heat-resistant oils that a...
