Colloidal nanocrystals have been intensively studied over the past three decades due to their unique properties that originate, in large part, from their nanometer-scale sizes. For applications in electronic and optoelectronic devices, colloidal nanoparticles are generally employed as assembled nanocrystal solids, rather than as individual particles. Consequently, tailoring 2D patterns as well as 3D architectures of assembled nanocrystals is critical for their various applications to micro- and nanoscale devices. Here, recent advances in the designed assembly, film fabrication, and printing/integration methods for colloidal nanocrystals are presented. The advantages and drawbacks of these methods are compared, and various device applications of assembled/integrated colloidal nanocrystal solids are discussed.

The preparation, formatting, and applications of colloidal nanoparticle solids have burgeoned tremendously over the last thirty years due to the remarkable crossover of ideas from many materials science fields. Here, general information on the preparation of colloidal nanocrystalline solids via thin-film formation and various printing techniques is presented. In addition, their integration into a number of advanced electronic applications is discussed.
