Organohalide perovskites have been witnessed as an emerging class of solution processable semiconductor with huge potential for applications in optoelectronic devices. However, a low-cost and high-yield patterning of these materials needs to be further improved. Herein, we demonstrated a facile approach to pattern perovskite nanocrystals embedded in polymer matrix by screen printing strategy. Importantly, this strategy achieves a champion photoluminescence quantum yield up to 96.5% and exhibited an intense green emission band centered at 517 nm with narrow full width at half-maximum of 20 nm. In addition, the composite films show an extraordinary stability in various environments, such as air, water, high temperature (80 degrees C), and Ultraviolet -radiation. The photoluminescence intensity of composite films decreases only 1.4% after being stored in air with 85% relative humidity for 3 months and remains 81.6% of initial values after being submerged in water for 3 months. Finally, we printed high-resolution patterns of 175 mu m, demonstrating that the screen printing is very promising for patterning perovskite composite microarrays.
