Title: Conductive transition metal oxide nanostructured electrochromic material and optical switching devices constructed thereof

Patent ·
OSTI ID:1398977
; ; ; ; ;

An electrochromic device includes a nanostructured transition metal oxide bronze layer that includes one or more transition metal oxide and one or more dopant, a solid state electrolyte, and a counter electrode. The nanostructured transition metal oxide bronze selectively modulates transmittance of near-infrared (NIR) spectrum and visible spectrum radiation as a function of an applied voltage to the device.
