Abstract
Methods of modifying the composition of layers using selectively absorbing films are described. The composition of a layer can be modified by applying a selectively absorbing film in proximity to the applied coating and components of the layer can be selectively removed to provide a modified layers. The methods can be used to increase the concentration of particles in the layer.
Claims13
A method of increasing the vol % of quantum dots in a first composition, comprising:
- (a) applying a selectively absorbing film in proximity to the first composition, wherein the first composition comprises a first vol % of quantum dots and at least one additional component, wherein the first vol % of quantum dots is based on the total volume of the first composition;
- and
- (b) modifying the first composition by causing the at least one additional component to absorb into the selectively absorbing film to provide a second composition, wherein,
- the second composition comprises a second vol % of the quantum dots, wherein the second vol % of quantum dots is based on the total volume of the second composition;
- and
- the second vol % is greater than the first vol %;
- and
- the at least one additional component comprises an acrylate monomer.
