Near-Field Direct Writing of the Photoluminescent Lattice Structures Pattern with RGB Colours Quantum Dots

Abstract:

The near-field direct writing technology represents a cutting-edge micro-nano additive manufacturing technique capable of printing intricate lattice structures with high precision. Leveraging the nanoscale self-luminous properties of quantum dots (QDs), a novel RGB QDs ink is developed by integrating QDs with polycaprolactone (PCL), specifically tailored for near-field direct writing applications. Based on the synergistic benefits offered by the aforementioned materials and technology, we present a groundbreaking approach to fabricating lattice structures patterns featuring RGB quantum dots. Firstly, a specialized printing ink is formulated for the production of lattice structures, aiming to achieve precise and intricate patterns. Subsequently, comprehensive investigations are conducted to determine the optimal parameters for the RGB quantum dots ink. Finally, an in-depth analysis is performed to evaluate the deposition process and luminescence properties of the resulting lattice structures pattern. The micron-scale lattice structures, incorporating quantum dots, hold great potential for applications in displacement encoders.
