Electrochromic properties of vanadium pentoxide thin films prepared by new wet process

Abstract

Electrochromic properties of the V,05 thin films prepared from a spinnable organic vanadium solution were investigated. The films heat-treated at 400 "C showed clear two-step electrochromism, deep blue F? greens yellow, with its response time for obtaining AOD = 0.5 being -2 s. The yellow and green colors showed good memory effects for more than 20 h, while the blue one was considerably degraded within 10 h.

Li+-intercalation electrochemical/electrochromic properties of vanadium pentoxide films by sol electrophoretic deposition

“…For example, the cathodic peak at −0.82 V in the 1st cycle shifts to −0.86 V in the 10th cycle. For both cycling in the 1.5-V range (0.4 V to −1.1 V) and the 2-V range (0.4 to −1.6 V), the shapes of CV curves closely resemble the voltammograms of V 2 O 5 film obtained by reactive dc magnetron sputtering and cycled in a 1.5-V region and a 2-V region, respectively [12] The results are also in a good agreement with those of V 2 O 5 films prepared by evaporation [33], electrochemical deposition [34], and spin-coating [35].…”

Electrochromic properties of V2O5−z thin films sputtered onto flexible PET/ITO substrates

“…Vanadium oxide has been prepared by a variety of methods, including evaporation [15,[20][21][22], d.c. sputtering [23], r.f. sputtering [24][25][26], pulsed laser deposition [27], plasmaenhanced chemical vapor deposition [28,29], electrochemical deposition [30][31][32] and sol-gel [33][34][35][36][37][38][39][40][41][42] preparations. However, the electrochromic performance of a-V 2 O 5 − z films deposited on Films were characterized to give insight into the nature of the coatings: the films' surfaces were studied by X-ray photoelectron spectroscopy (XPS) and field emitted scanning electron microscopy (FESEM).…”

Structural, Optical and Electrochromic Properties of Sol–Gel V2O5Thin Films

“…For some applications, microporous solgel thin films may be appropriate. V 2 O 5 thin films have been prepared from gels using either spin-coating [3][4][5][6] or dip-coating [7][8][9] methods. The aim of this work is to present a structural, optical and electrochromic study of V 2 O 5 thin films prepared by sol-gel spin coating route.…”
