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 method of hermetically sealing one or more compositions comprising a plurality of luminescent nanocrystals, the method comprising:
- (a) providing a first substrate;
- (b) disposing one or more compositions comprising a plurality of luminescent nanocrystals onto the first substrate;
- (c) disposing a second substrate on the first substrate so as to cover the compositions of luminescent nanocrystals;
- and
- (d) sealing the first and second substrates;
- ;
- and
- e) disposing a first barrier layer on the first substrate and a second barrier layer on the second substrate which is configured to reduce or eliminate the passage of moisture and/or air to the nanocrystals, which first and second barrier layer comprises an inorganic layer of SiO2 or AlO2.
