Summary from Kohesio (English machine translation by the source): The aim of the project is to obtain fluorescent ink, containing dispersed, semiconductor, colloidal quantum dots. This ink will be used to print optoelectronic elements. The purpose of the ink results from a special feature of quantum dots, i.e. efficient and selective absorption and emission of light, and the possibility of converting electricity into light and vice versa. Thus, the developed ink can be used to produce printing techniques such as photovoltaic cells and displays. The ink will be optimised for use in inkjet printers. In the process of optimising ink, emphasis will be placed on the possibility of printing in high spatial resolution, on flexible substrates, in particular transparent polymer films (e.g. PET, PVK) The project consists of 3 stages of development: — Phase 1 – functionalisation of the surface of quantum dots; — Phase 2 – ink formulation based on functionalised quantum dots; — Phase 3 – Optimisation of ink and its printing parameters for high resolution applications. As a result of the work done, we expect to obtain two types of ink, one based on polar solvents, the other on non-polar solvents. These two types of ink will be complementary, i.e. thanks to their alternating printing it will be possible to create multilayer optoelectronic structures (e.g. multicolored pixels, structures with more efficient interaction with light). At all stages of the project, extensive methodologies and test/characterisation methods will be used to obtain a high-quality product that meets the requirements of advanced, printed optoelectronics. The project will also include an installation enabling the functionalisation of the surface and formulation of the ink on a pilot scale.
