Achieving both high stability and high resolution patterning in halide perovskite nanocrystals (PNCs) is difficult, limiting their practical applications in full color displays despite of their promising optical properties. Here we introduce the direct optical patterning of PNC/siloxane nanocomposites, which increases the stability of PNC patterns. Multicolored patterning of PNC/siloxane nanocomposites was demonstrated by sequentially controlling the rheology of the PNC/siloxane nanocomposites, such as reducing high viscosity and consequently increasing the elastic behavior in patterning process. The patterned PNCs maintained stable PLQE in harsh environments such as water, high temperature (40 ℃) with high relative humidity (70% RH), which provide the breakthrough for PNC-based color conversion layers.
