20.500.12556/DKUM-67453 EXAFS and IR analysis of electrochromic $NiO_x$/$NiO_xH_y$ thin films Electrochromic (EC) thin films of $NiO_x$ and $NiO_xH_y$ are prepared by sol-gel method from nickel chloride precursor and deposited onto a suitable substrate by dip-coating technique. The development of the structure with thermal treatment is investigated by EXAFS and IR spectroscopy in two series of films, with high and low concentration of chloride as counter ions. In the former, the predominant structure before thermal treatment is nickel hydroxide. The baking induces condensation, yet with no trace of NiO. In the latter group, colloidal particles are indicated, on which acetate groups are adsorbed or coordinated. At the maximum EC-response the formation of NiO grains is established by EXAFS and IR. Elektrokromne tanke plasti $NiO_x$ in $NiO_xH_y$ smo pripravili z metodo sol-gel iz nikelj-kloridnega prekurzorja in jih s tehniko potapljanja nanesli na ustrezno podlago. Razvoj strukture s temperaturo obdelave smo spremljali s spektroskopijama EXAFS in IR pri dveh serijah filmov z visoko oz. nizko koncentracijo kloridnih proti-ionov. V prvi pred termično obdelavo prevladuje struktura nikljevega hidroksida. Segrevanje nato izzove kondenzacijo, vendar brez sledov NiO. V drugi seriji so prisotni koloidni delci, na katere so adsorbirane acetatne skupine. Z obema spektroskopskima metodama smo pri plasteh z največjim elektrokromnim odzivom ugotovili prisotnost strukture nikljevega oksida. electrochromism thin films nickel oxide nickel hydroxide EXAFS anorganska kemija analitska kemija elektrokemija elektrokromizem elektrokromni materiali tanki filmi sol-gel postopek analiza elektrokromnih tankih filmov EXAFS IR spektroskopija nikljevi oksidi NiO nikljev hidroksid nikelj prekurzorji true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-08-18 11:45:32 2017-08-18 11:47:16 2022-08-01 13:59:52 2019-07-11 16:20:56 2008 0 0 str. 154-159 št. 1 Letn. 55 2008 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1318-0207 543.422.3-74:544.6:546.74-31.022 14086149 29362693 1318-0207 URN:SI:UM:DK:9BWIAZFU Acta_Chimica_Slovenica_2008_Padeznik_Gomilsek_et_al._EXAFS_and_IR_analysis_of_electrochromic_NiOsubxNiOsubxHsuby_thin_films.pdf Acta_Chimica_Slovenica_2008_Padeznik_Gomilsek_et_al._EXAFS_and_IR_analysis_of_electrochromic_NiOsubxNiOsubxHsuby_thin_films.pdf 1 A2456E6CD8A01833ADA804046A52EF85 f721573d9091175d2cc80ddddbfc6439ad22dabc376c0cfcf5b50789a7170ae5 877755ab-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/6a672684-ceab-46d7-894e-573698f0155b https://dk.um.si/Dokument.php?lang=slv&id=115517 http://acta-arhiv.chem-soc.si/55/55-1-154.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=115516 Fakulteta za strojništvo 0 0 0
