TLDR
A brief summary of the recent progress in tungsten oxide for optoelectronic applications is provided, including not only the traditional field of electrochromism/photochromism, but also new areas of application, such as visible-light-driven photocatalysis, photothermal therapy, and surface enhanced Raman spectroscopy (SERS).Abstract:
Tungsten oxide is a versatile transition-metal oxide with a vast number of polymorphs and sub-stoichiometric compositions, featuring innate tunnels and oxygen vacancies. The structure-determined nature, such as altered optical absorption and metal-like conductivity, makes tungsten oxide an attractive candidate for optoelectronic applications. A brief summary of the recent progress in tungsten oxide for optoelectronic applications is provided, including not only the traditional field of electrochromism/photochromism, but also new areas of application, such as visible-light-driven photocatalysis, photothermal therapy, and surface enhanced Raman spectroscopy (SERS). Also, the prospects for future applications of tungsten oxide are summarized and highlighted.read more
