Patent ID: 8530883

Claim:
A light emitting device comprising: a.) a substrate having one or more excitation sites; b.) one or more excitation sources operatively coupled to the one or more excitation sites, the one or more excitation sources at least in part configured for excitation of quantum dots; and c.) a conversion layer adjacent to the substrate, the conversion layer containing quantum dots suspended in a light-transmissive material; wherein the conversion layer is provided by: i.) providing a fluid in a container, the fluid carrying quantum dots; ii.) applying an acoustic field within the fluid; iii.) allowing the acoustic field to cause the quantum dots to accumulate at one or more predetermined locations corresponding to the excitation sites; iv.) monitoring a distribution of the quantum dots within the fluid; and v.) initiating a phase transition of the fluid based at least in part on the monitored distribution of the quantum dots, thereby trapping the quantum dots at the predetermined locations.
