Abstract
The present invention provides methods for hermetically sealing luminescent nanocrystals, as well as compositions and containers comprising hermetically sealed luminescent nanocrystals. By hermetically sealing the luminescent nanocrystals, enhanced lifetime and luminescence can be achieved.
Claims14
A microsphere comprising:
- a composition comprising:
- luminescent core-shell nanocrystals;
- and
- an inorganic layer covering each of the luminescent core-shell nanocrystals;
- and
- a barrier layer, disposed on the inorganic layer, configured to hermetically seal the composition, wherein the barrier layer consists essentially of SiO2, TiO2, or Al2O3.
3 more elements
A method comprising:
- forming a composition comprising:
- luminescent core-shell nanocrystals coated with an inorganic layer, and
- an inorganic layer covering each of the luminescent core-shell nanocrystals;
- and
- disposing a barrier layer on the inorganic layer to hermetically seal the composition, wherein the barrier layer consists essentially of SiO2, TiO2, or Al2O3.
2 more elements
A composition comprising:
- luminescent core-shell nanocrystals;
- a hydrophilic layer covering each of the luminescent core-shell nanocrystals;
- and
- a hydrophobic layer, disposed on the hydrophilic layer, configured to hermetically seal the composition.
