Abstract
In recent years, lanthanide metal organic frameworks have been widely used in various fields because of their excellent fluorescence properties. Fluorescence switch has also been considered as a research hot spot and widely applied in many fields. The combination of fluorescent material and electrochromic material has emerged in the preparation of fluorescence switch. Herein, a simple and rapid electrodeposition method is proposed for the preparation of amorphous EuMOF film. The whole process takes only half an hour under room temperature. The prepared amorphous EuMOF film exhibits significant emission peaks characteristic of Eu3+ when excited by 277 nm UV lamp. In addition, the prepared EuMOF is also applied in an electrochromic device to construct WO3/EuMOF fluorescence switch by stepwise electrodeposition using polystyrene microsphere as template. By changing the voltage, the coloring and fading of the device color, and the quenching and recovery of fluorescence can be reversibly regulated, in order to achieve the control of the “on” and “off” states of the fluorescence switch.
