We present a process flow that begins with the synthesis of cadmium-free quantum dots (QDs) and leads to the formulation of a solvent-free, acrylate-based ink. This work emphasizes the importance of the QDs surface chemistry modification to ensure QD stability and processability under ambient conditions, while maintaining their optical properties, efficiency and photostability.
