Abstract Nanosized coordination polymers (NCPs) and their thin films with tunable full-color fluorescence emission, simple preparation, and good biocompatibility are highly desirable for optical and biomedical applications. Changes in the reaction conditions for fluorescent NCP@PEI and its thin films with tunable full-color emission are the first to be presented as the result of surface modification of PEI-induced band gap changes. Significantly, a white emitting fluorescence-calculated CIE value of (0.308, 0.312) can be observed by mixing NCP@PEI, and NCP@PEI-based poly (vinyl alcohol) (PVA) films with tunable full-color emission were obtained. The reaction condition effect is of particular importance for optical applications, where it can provide a new route to design NCP- or metal organic framework-based materials.
