tailieunhanh - Characterization of structural and electrochromic properties of nanocomposite TiO2 −WO3 films

The reversible coloration and bleaching of TiO2/ITO and WO3-TiO2/ITO electrodes were demonstrated. The ECD coloration efficiency of WO3-TiO2/ITO was found to be much larger ( cm2 × C −1 ) than that of TiO2/ITO ( cm2×C −1 ). The resulting nanostructured composites enables the coloration efficiency of the WO3-TiO2 film to be considerably improved. The results suggest a potential application of the nanocomposites of two electrochromic oxides in large-area energy-efficiency (or smart) windows. | Communications in Physics, Vol. 24, No. 3S1 (2014), pp. 57-63 DOI: CHARACTERIZATION OF STRUCTURAL AND ELECTROCHROMIC PROPERTIES OF NANOCOMPOSITE TiO2 − WO3 FILMS DANG HAI NINH, TRAN THI THAO, AND NGUYEN NANG DINH University of Engineering and Technology, Vietnam National University, Hanoi PHAM DUY LONG Institute of Materials Science, Vietnam Academy of Science and Technology E-mail: dinhnn@ Received 04 April 2014 Accepted for publication 24 May 2014 Abstract. Using doctor-blade technique, followed by electrochemical deposition, nanocomposite WO3 -TiO2 films were prepared. Structure, morphology and composition ratio of the nanocomposite films were characterized by a comprehensive analyzing the SEM, EDX, XRD and Raman scattering results. The reversible coloration and bleaching of TiO2 /ITO and WO3 -TiO2 /ITO electrodes were demonstrated. The ECD coloration efficiency of WO3 -TiO2 /ITO was found to be much larger ( cm2 × C−1 ) than that of TiO2 /ITO ( cm2 ×C−1 ). The resulting nanostructured composites enables the coloration efficiency of the WO3 -TiO2 film to be considerably improved. The results suggest a potential application of the nanocomposites of two electrochromic oxides in large-area energy-efficiency (or smart) windows. Keywords: electrochromic display (ECD), electrochemical deposition, SEM and EDX, XRD and Raman scattering, coloration efficiency. I. INTRODUCTION Electrochromic display (ECD) has been investigated extensively in the last decades because of its potential applications in light controlling, energy-efficient or smart windows [1]. ECD properties can be found in almost all the transition-metal oxides and they can be coloured anodically (Ir, Ni) or cathodically (W, Ti) [1–3]. Recently Granqvist et al [4] have made a comprehensive review of nanomaterials for benign indoor environments. In this report, the authors show the characteristic data for a 5 × 5 cm2 flexible ECD foil incorporating WO3 , and .
