Polymer-Assisted High-Resolution Printing Techniques for Colloidal Quantum Dots
E-mail:,
Over the last several decades, colloidal quantum dots (QDs) have been widely studied because of their unique optical and electronical properties such as band gap tunability, extremely high color purity, and efficient light absorption and emission. Consequently, they have been regarded as promising materials for nextgeneration optoelectronic devices such as displays, image sensors, and solar cells. Because these devices employ solid state forms of colloidal QD ensembles, the development of the processes that can tailor their 3D architecture is essential. Here, this review article explores the recent progress of the high-resolution printing techniques for colloidal QDs. Specifically, we present a wide range of methods including photolithography, inkjet printing, nanoimprinting, and transfer printing. We also discuss how these printing methods have been inspired by the patterning techniques for polymer-based materials.
