Abstract:
1. A method of forming an ink, comprising: providing a set of Group IV semiconductor nanoparticles, wherein each Group IV semiconductor nanoparticle of the set of Group IV semiconductor nanoparticles includes a nanoparticle surface with a first exposed nanoparticle surface area; reacting the set of Group IV semiconductor nanoparticles to a set of bulky capping agent molecules resulting in a second exposed nanoparticle surface area, wherein the second exposed nanoparticle surface area is less than the first exposed nanoparticle surface area; and dispersing the set of Group IV semiconductor nanoparticles in a vehicle; wherein the ink is formed, further wherein the ink and the bulky capping agent molecules are adapted to provide a densified film from the ink, the densified film suitable for use in an optoelectronic device, and further wherein the step of reacting the set of Group IV semiconductor nanoparticles to a set of bulky capping agent molecules further includes:
