Abstract
A photoconductor and method of forming a photoconductor comprising forming a charge generation material comprising a plurality of quantum dots, and forming an active region comprising one or more photoconductor layers comprising the charge generation material including the surface modified quantum dots is disclosed.
Claims16
A photoconductor for an electrophotographic device comprising:
- at least one conductive layer and;
- an active region comprising at least one photoconductor layer comprising:
- a charge generation material (CGM) comprising a plurality of surface modified quantum dots, wherein the quantum dots are formed by depopulation of the organic ligands forming the capping layer of the quantum dots.
A method of forming surface modified quantum dots (QD) comprising:
- recovering a plurality of surface-depopulated QDs from a QD sample comprising a plurality of QDs each having an organic capping layer;
- and
- forming a QD photoconductor material including the surface-depopulated QDs for an electrophotographic device.
