Abstract
A method of storing and transporting quantum dot formulations is provided. The method includes storing and/or transporting the quantum dot formulation under an oxygen-containing atmosphere. A sparged and degassed quantum dot formulation is also described.
Claims13
A method of processing a quantum dot formulation including oxygen comprising:
- providing in a reaction vessel the quantum dot formulation;
- where the quantum dot formulation comprises quantum dots and a liquid formulation;
- and the liquid formulation comprises an unpolymerized polymerizable component and an inhibitor compound, which requires oxygen to inhibit polymerization;
- displacing the oxygen with an inert gas by sparging the quantum dot formulation with the inert gas;
- and
- degassing the quantum dot formulation in the reaction vessel.

A method of processing a quantum dot formulation including dissolved oxygen comprising:
- introducing an inert gas into the quantum dot formulation for a time period sufficient to remove substantially all oxygen from the quantum dot formulation;
- where the quantum dot formulation is contained in a reaction vessel, and the quantum dot formulation comprises an unpolymerized polymerizable component and an inhibitor compound, which requires oxygen to inhibit polymerization;
- subjecting the quantum dot formulation to vacuum while under agitation;
- and
- degassing the quantum dot formulation to remove substantially all dissolved gas from the quantum dot formulation in the reaction vessel.
