“…Recently, the electrochromic materials gain a lot of attention due to the energy saving applications and usage as smart windows [11], anti-glared rear view mirrors [12], and displays [13]. Electrochromic material (often in thin film form) is a part of electrochromic device [14], which is typically consisted of several components (see figure 1): a glass substrate covered by transparent conducting oxide (TCO); an EC film (transition metal oxides and mostly WO 3 ); an ion conductor (IC) (a polymer electrolyte or solid one); a counter electrode -often this is also conductive glass substrate with anodic type electrochromic functional film.…”

Abstract. "Smart windows" are envisaged for future low-energy, high-efficient architectural buildings, as well as for the car industry. By switching from coloured to fully bleached state, these windows regulate the energy of solar flux entering the interior. Functional layers in these devices are the transition metals oxides. The materials (transitional metal oxides) used in smart windows can be also applied as photoelectrodes in water splitting photocells for hydrogen production or as photocatalytic materials for self-cleaning surfaces, waste water treatment and pollution removal. Solar energy utilization is recently in the main scope of numerous world research laboratories and energy organizations, working on protection against conventional fuel exhaustion. The paper presents results from research on transition metal oxide thin films, fabricated by different methods -atomic layer deposition, atmospheric pressure chemical vapour deposition, physical vapour deposition, and wet chemical methods, suitable for flowthrough production process. The lower price of the chemical deposition processes is especially important when the method is related to large-scale glazing applications. Conclusions are derived about which processes are recently considered as most prospective, related to electrochromic materials and devices manufacturing. Transition metal oxidesTransition metal oxides (TMO) are claimed to be one of the most interesting classes of solids, exhibiting varieties of properties, structures and applications [1]. Their properties are determined by the unique nature of their outer d-electrons. Transition-metal oxides can be insulators, semiconductors, metals, or undergo semiconductor-metal transitions. Transition metal oxides possess unusual and useful electronic, optical and magnetic properties. Many of these properties strongly depend on materials defects like vacancies, dislocations, stacking faults and grain boundaries [2].

“…Tungsten oxide has been widely investigated because of their potential applications [1][2], such as in gas sensors [3][4][5], in catalytic, photochromic [6][7], excellent electrochromic devices [8][9] and the ability to accumulate charges [10]. However, their electrochromic properties and their optical characteristics have been focused much with hopes about some smart windows.…”

Abstract. In this paper we report the synthesis of WO3 thin films and investigate the effect of the structure on their optical properties. The WO3 thin films are coated on glass substrates from both W and WO3 targets by the magnetron sputtering method in (Ar+O2) plasma under different deposition temperatures, varying from room temperature to 480˚C. We also evaluate the band gap energy of WO3 by considering the transitions between the valence and the conduction bands. This result suggests that the best choices are diagonal and allowed transitions. Based on the values of band gap energy and XRD pattern, we indicate the relationship between crystalline order and optical property and consequently, the difference in color of the samples.

“…Considering the wide scope of electrochemical studies and their possible exploitation, attention has been currently paid to the preparation of a number of analogues of PB as revealed by the growing number of references on this subject. [40][41][42][43][44][45][46][47][48][49][50][51] It is of interest that on careful examination of different reports on metal hexacyanoferrate (PB analogue) modified electrodes and their redox characteristics published so far, it is apparent that only few have involved studies on the detailed process of preparation of PB and its analogue CME, particularly that of manganese hexacyanoferrate (MnHCF), which is crucial to the chemical or electrochemical deposition of thin films of transition metal hexacyanometallates onto a number of different conducting substrate electrodes such as glassy carbon, gold, platinum, indium-tin oxide, etc.…”

A thin film of manganese hexacyanoferrate (MnHCF) was electrochemically formed on a glassy carbon (GC) electrode to prepare a chemically modified electrode (CME). The mechanism of film formation of MnHCF and its growth process were investigated in detail by cyclic voltammetry. The results show that the stoichiometric composition of MnHCF is Mn III Fe III (CN) 6 , an analogue of prussian yellow. There exist three clear-cut stages in the whole modification process and the last stage is indispensable to the fabrication of homogenized, stable MnHCF film and must last for an appropriate time. The surface morphology of MnHCF/GC electrode was characterized by scanning electron microscopy (SEM), which further verified the effective deposition of MnHCF film on GC. The kinetic constants of MnHCF/GC electrode process were also evaluated. The resulting MnHCF film modified electrode presented good stability and high electrocatalytic activity toward the oxidation of H 2 O 2 , indicating that MnHCF film possesses function of catalase and can be expected for analytical purposes.
