Beschreibung
Zusammenfassung:	The invention discloses an electrochromic film with neutral coloring and a preparation method and application thereof. The preparation method comprises the steps that a W-Nb-O electrochromic material is provided and comprises Nb2O5 and WO3, the content of the Nb2O5 is 30-70 wt%, and the content of the WO3 is 30-70 wt%; the W-Nb-O electrochromic film with neutral coloring is prepared by adopting a magnetron sputtering technology and combining with a high-temperature thermal annealing technology which is selectively carried out or not carried out. The W-Nb-O electrochromic film prepared by the invention has better optical modulation amplitude, cycling stability, excellent colored neutral color and electrochromic performance, and can meet better application prospects in neutral color electrochromic devices. 本发明公开了一种具有中性着色的电致变色薄膜及其制备方法与应用。所述制备方法包括：提供W-Nb-O电致变色材料，包括Nb2O5和WO3，其中，Nb2O5的含量为30～70wt％；采用磁控溅射技术，结合选择性进行或不进行的高温热退火技术，制备出具备中性着色的W-Nb-O电致变色薄膜。本发明制得的W-Nb-O电致变色薄膜具有较好的光学调制幅度、循环稳定性、优异的着色态中性色以及电致变色性能，能满足其在中性色电致变色器件
