WO_(3) Inversce Opal Photonic Crystals: Unique Property, Synthetic Methods and Extensive Application

Tungsten trioxide inverse opal photonic crystals(WO_(3) IOPCs)not only possess the intrinsic properties of WO_(3)/but also own the unique characteristics of lOPCs structure.The evolution of preparation method of WO_(3) IOPCs has been briefly presented as electrodeposition method,sol-gel methodology and’dynamic hard-template’strategy in this review.Then the crystalline structure,optical property and electrical performance of WO_(3) IOPCs are later described.Afterwards,this review focuses on the wide application of WO_(3) lOPCs in chemical sensor,photo(electro)catalysis,electrochromic material and photochromic field in the last decade.Finally,a brief outlook over future investigation in preparation and modification,as well as promising application is proposed.This paper aims to encourage the attention and effort of researchers on WO_(3) IOPCs and other semiconductor materials with lOPCs structure.
