Synthesis and characterization of tungsten based mixed valence state nanoparticles and their novel applications are reviewed. The mixed valence state tungsten based homogeneous nanomaterials such as bronze structure MxWO3 (M = Na+, K+, Rb+, Cs+, NH4+, etc.) and tungsten sub-oxide W18O49 possess excellent infrared (IR) light shielding property, implying their great potential applications on heat ray shielding and indoor energy saving effect in summer season. Also, some novel properties such as electric conductivity, bio thermal therapy function and electrochromic properties of mixed valence state tungsten based materials are introduced. The design of components, formation of composites and structure control of thin films are expected to realize the property enhancement and candidates for practice application as window materials. The multifunctionality of the mixed valence state based composites also implies great potential on novel applications of various building materials.
