摘要
Traditional inkjet printing color quantum dot technology is to print red, green and blue quantum dot inks respectively, while perovskite material is ionic compound, and changing the halogen component can change the light color, which provides a new method for inkjet printing to realize color display. Here, we report a method for implementing blue devices by ion exchange between halogen‐containing inks and underlying perovskite quantum dot films by inkjet‐printing. This method can also be used for full‐color devices.
