Optical and structural characterization of nickel oxide-based thin films obtained by chemical bath deposition

Electrochromism in nickel oxide-based thin films obtained by chemical bath deposition

“…Previously we reported the optical and structural properties of CBD-formed nickel oxide-based films using a proper formulation [12]. In the present work, we report electrochromic properties of films obtained in the same way, but after different annealing conditions.…”

Thermal, IR, Raman characteristics, Raman gain coefficient and bandwidths in quaternary glasses

“…A band labeled (B) around 475e563 cm À1 can be attributed to TeeOeW or TeeOeR linkages where R ¼ Ti, Mn, Ni and Cu [17]. A band labeled (C) around 575e601 can be attributed the stretching [TeO 4 ] trigonal pyramid with bridging oxygen and may be assigned to the stretching vibrations of CueO (in sample 1), AgeO vibrations (sample 4) [18,19], TieO vibrations in octahedral TiO 6 (sample7) [20], the stretching vibrations of NieO (sample 3) [21]. A very strong band labeled (D) around 657e685 cm À1 is assigned to stretching vibrations of TeO 4 tbp [22,15,16,23,24].…”

Influence of temperature on the characteristics of Ni(II), Ti(IV) layered double hydroxides synthesised by different methods

“…LDH with tetravalent cations such as Ti 4+ [2,3], Zr 4+ [4], V 4+ [5] are also described in the literature. Ni-Ti LDH, which can also be characterized as titaniumstabilized α-Ni(OH) 2 , are widely used in the same fields as nickel hydroxide: а) as electrode materials for power sources, such as lamellar alkaline accumulators [6,7], supercapacitors with composite [8] or individual film electrodes [9], supercapacitors and alkaline accumulators with pasted electrodes [10]; b) as electrochromic films for devices based on nickel hydroxide [11], Ni-Al LDH [12], Ni LDH with various cations [13]; c) as a catalyst for electrooxidation of various organic compounds [14], including methanol [15,16].…”
