Inorganic dopants, inks and related nanotechnology
First Claim
1. An ink composition comprising:
- inorganic multimetallic nanofillers with domain size less than 100 nanometers;
a solvent;
wherein the nanofillers are dispersed in the solvent; and
wherein the nanofillers exhibit transparency to a visible wavelength of light that differs by more than 20% as compared with transparency to the visible wavelength of light exhibited by fillers of similar composition with fillers having a domain size of at least one micron.
