This paper reports the enhancement of the electrochromic properties in the infrared, IR,region of radio frequency sputtered WO3 thin films thanks to a careful optimization of thedeposition conditions. From the combination of various techniques of characterization, the opticalperformances, in particular, the contrast in reflectance between the inserted state and the deinsertedone, upon cycling in H3PO4 liquid electrolyte, are correlated to the film morphology andcomposition. Films, grown in higher chamber pressure, exhibiting a lower density and a O/W ratiohigher than 3, show the most promising behavior. Finally, first trends on the incorporation of theWO3 single layer in full electrochromic devices are discussed
