Abstract

A method comprising depositing an ink comprising a nanomaterial, a material capable of transporting charge, and a liquid vehicle from a micro-dispenser onto a layer of a device is disclosed. A method comprising depositing an ink comprising a nanomaterial, a material capable of transporting charge, and a liquid vehicle from a micro-dispenser onto a second material capable of transporting charge in a predetermined arrangement is also disclosed. In certain preferred embodiments, the nanomaterial comprises semiconductor nanocrystals. In certain preferred embodiments, a micro-dispenser comprises an inkjet printhead. Methods for fabricating devices including a nanomaterial and method for fabricating an array of devices including a nanomaterial are also disclosed. An ink composition including a nanomaterial, a material capable of transporting charge, and a liquid vehicle is also disclosed.
