In this study we investigated the electrochromic properties and electrochromic device application of poly(5,12-dihydrothieno[3',4':2,3][1,4]dioxocino[6,7-b]quinoxaline (DDQ)-co-2,2'-bithiophene (13T)). Copolymerization was successfully achieved electrochemically in acetonitrile containing 0.1 M tetrabutyl ammonium tetrafluoroborate as the supporting electrolyte by direct anodic oxidation on platinum and indium tin oxide coated glass electrodes. The structure and morphology of the copolymer were investigated by infrared spectroscopy and scanning electron microscopy (SEM). Spectroelectrochemical analysis of the resulting copolymer reflected electronic transitions at 504 nm and similar to 800 nm revealing a pi-pi* transition and polaron formation, respectively. Dual-type polymer electrochromic devices (ECDs) based on P(DDQ-co-BT) were constructed with poly(3,4-ethylenedioxythiophene) (PEDOT). Spectroelectrochemistry, switching ability and stability experiments showed that the copolymer concerned can be a good anode material for electrochromic devices.

Improving electrochromic properties via copolymerization Taskin, Asli Tuba; Balan, Abidin; Udum, Yasemin Arslan; Toppare, Levent Kamil (IOP Publishing, 2010-06-01) Copolymers of 5,8-di(1H-pyrrol-2-yl)-2,3-di(thiophen-2-yl) quinoxaline (PTQ) in the presence of 2,2'-bis(3,4-ethylenedioxythiophene) (BiEDOT) and 4,7-bis(2,3-dihydrothieno[3,4-b][1,4] dioxin-5-yl)-2-dodecyl-2H-benzo[1,2,3] triazole (BEBT) were synthesized via the potentiodynamic method in a tetrabutylammonium perchlorate/dichloromethane (TBAP/DCM) (0.1 M) solvent-electrolyte couple. P(PTQ-co-BiEDOT) reveals an oxidation potential at +0.45 V and a reduction potential at -0.2 V (figure 1(a)), whereas the homo...
Comparison of magnetic Barkhausen noise and ultrasonic velocity measurements for microstructure evaluation of SAE 1040 and SAE 4140 steels Gür, Cemil Hakan; Çam, İbrahim (Elsevier BV, 2007-05-01) The aim of this study is to compare the performance of magnetic Barkhausen noise and ultrasonic methods for the evaluation of the microstructure of commercial steels. Following the austenitization of the specimens made of SAE 1040 and SAE 4140, various heat treatments were carried out to obtain microstructures consisting of martensite, tempered martensite, fine pearlite-ferrite, and coarse pearlite-ferrite. The microstructures were initially characterized by SEM investigation and hardness measurements. The ...
Enhancing electrochemical and electrochromic performances of carbazole comprising monomer via copolymerization with 3,4-ethylenedioxythiophene (EDOT) Kalay, Isil; Yigit, Deniz; GÜLLÜ, Mustafa; DEPCİ, TOLGA; Toppare, Levent Kamil; Hacioglu, Serife O. (Elsevier BV, 2020-09-01) In this study, two novel electrochromic copolymers (CoP1.3 and CoP1.5) were synthesized via electrochemical methods and characterized. The comonomers used in the synthesis were 3,4-ethylenedioxythiophene (EDOT) and a carbazole comprising monomer; 9-(2-(4-(Phenyldiazenyl) phenoxy) ethyl)-3,6-di(thiophen-2-yl)-9H-carbazole (M1). Carbazole containing monomer (M1) and EDOT were combined with two different comonomer feed ratios, 1: 3 and 1: 5 respectively in order to investigate the effect of increasing EDOT amo...
CZTSSe thin films fabricated by single step deposition for superstrate solar cell applications Terlemezoğlu, Makbule; Dogru, C.; Gullu, H. H.; Çiftpınar, Emine Hande; Parlak, Mehmet (Springer Science and Business Media LLC, 2019-06-01) The focus of this study is the characterization of Cu2ZnSn(S,Se)(4) (CZTSSe) thin films and fabrication of CZTSSe solar cell in superstrate configuration. In this work, superstrate-type configuration of glass/ITO/CdS/CZTSSe/Au was entirely fabricated by totally vacuum-based process. CZTSSe absorber layers were grown by RF magnetron sputtering technique using stacked layer procedure. SnS, CuSe and ZnSe solid targets were used as precursors and no additional step like the selenization process was applied. The...
Thermoluminescence characterization of (Ga2Se3)(0.25) - (Ga2S3)(0.75) single crystal compounds Isik, M.; Guler, I; Hasanlı, Nızamı (Elsevier BV, 2020-03-15) Ga2Se3 and Ga2S3 compounds take attention due to their potential applications in photovoltaics. Defects and impurities may affect the quality of optoelectronic devices. Therefore, it is worthwhile to determine the parameters (activation energy, order of kinetics, frequency factor) of traps associated with the defects and/or impurities. The aim of the present paper is to investigate the trapping parameters of (Ga2Se3)(0.25) - (Ga2S3)(0.75) single crystal which is one of the member of (Ga2Se3)(x) - (Ga2S3)(1-...
