Advancing microarray fabrication: One-pot synthesis and high-resolution patterning of UV-crosslinkable perovskite quantum dots
The development of highly efficient, solution-processable, and environmentally stable perovskite quantum dots (PQDs) is crucial for their accurate high-resolution patterning and subsequently enabling the practical deployment of PQD based emissive display devices. This study presents an innovative strategy for integrating all-inorganic PQDs and ultraviolet (UV) crosslinkable acrylate polymer at a structural and functional level. The achievement is accomplished by meticulous design and one-pot synthesis of UV-crosslinkable CsPbX3 (X = Cl, Br, I) PQDs solution, which exhibit outstanding environmental stability. Leveraging the solution-processable characteristics of the resulting UV-crosslinkable PQDs, precise patterning of high-resolution (2 µm, 7608 pixels in.−1) and colorful PQDs microarrays can be readily achieved through inkjet printing and high-throughput photolithography (~ 2 µm in pitch line/space patterning). The UV cross-linked process guarantees a homogeneous distribution of PQDs, effectively mitigating coffee ring effect and improving the overall quality of stereoscopic microarrays. The photo-cured PQDs film, which undergoes free radical photopolymerization, displays an impressive photoluminescence quantum yield (PL QY) of up to 89.2%, reaching 98% of the value observed in the solution state. The approach outlined in this research is both cost-effective and pragmatic, exhibiting tremendous promise for diverse system-level integrated optoelectronic devices, such as ultra-high-resolution micro-light-emitting device (micro-LED) displays.
