Abstract
Quantum dot delivery methods are described. In a first example, a method of delivering or storing a plurality of nano-particles involves providing a plurality of nano-particles. The method also involves forming a dispersion of the plurality of nano-particles in a medium for delivery or storage, wherein the medium is free of organic solvent. In a second example, a method of delivering or storing a plurality of nano-particles involves providing a plurality of nano-particles in an organic solvent. The method also involves drying the plurality of nano-particles for delivery or storage, the drying removing entirely all of the organic solvent.
