Abstract

Plate-like hydrated tungsten trioxide (3WO(3)·H(2)O) films were grown on a fluorine doped tin oxide (FTO) coated transparent conductive substrate via an efficient, facile and template-free hydrothermal method. The film exhibited a fast coloration/bleaching response (t(c90%) = 4.3 s and t(b90%) = 1.4 s) and a high coloration efficiency (112.7 cm(2) C(-1)), which were probably due to a large surface area.

摘要

片状水合三氧化钨 (3WO(3)·H(2)O) 薄膜通过高效、简便且无模板的水热法在掺氟氧化锡 (FTO) 涂覆的透明导电基底上生长。该薄膜表现出快速的着色/褪色响应（t(c90%) = 4.3 s 和 t(b90%) = 1.4 s）和高的着色效率（112.7 cm(2) C(-1)），这可能是由于其具有较大的比表面积。
