US Patent 8023306 - Electronic and optoelectronic devices with quantum dot films

Thin patent from InVisage Technologies teaches how fused quantum dots can be integated into CCD or CMOS imaging arrays. Claim 1 reads:

1. A film comprising a network of fused nanocrystals,

the nanocrystals having a core and an outer surface,

wherein the core of at least a portion of the fused nanocrystals is in direct physical contact and electrical communication with the core of at least one adjacent fused nanocrystal,

the outer surface including a semiconductor material,

the film having substantially no defect states in the regions where the cores of the nanocrystals are fused.
