Patent ID: 8182721

Claim:
A method for fabricating a liquid containing intermixed elements of groups IB and IIIA, comprising the steps of: forming non-oxide nanoparticles containing elemental elements from group IB, IIIA, and VIA; intermixing the non-oxide nanoparticles; and mixing the non-oxide nanoparticles to form a liquid that serves as an ink, wherein forming a mixture of non-oxide nanoparticles includes a reaction of the type: (IB)(Hal)+(IIIA)(Hal)+Na 2 (VIA)+Ligand/Capping Agent→IB-IIIA-VIA, where IB refers to an element of group IB, IIIA refers to an element of group IIIA, VIA refers to an element of group VIA and Hal refers to a halogen.
