Let us add here that the fabrication of polycrystalline semiconductive films with enhanced photoresponse and increased resistance to electrochemical corrosion has been attempted by introducing semiconductor particles of colloidal dimensions to bulk deposited films, following the well-developed practice of producing composite metal and alloy deposits with improved thermal, mechanical, or anti-corrosion properties. Eor instance, it has been reported that colloidal cadmium sulfide [105] or mercuric sulfide [106] inclusions significanfly improve photoactivity and corrosion resistance of electrodeposited cadmium selenide.

Spray painted (spray deposited) titanium dioxide coatings were sensitized [205] with chemically deposited cadmium selenide thin films the structural, optical, and pho-toelectrochemical characterization of these composite films indicate the importance of thermal treatments in improving the photocurrent quantum yields. Up to 400 °C, the effect of air annealing is to shift the onset of absorption to longer wavelengths and improve the photocurrent substantially. [Pg.12]

Mixed alkyl/dithio- or diselenocarbamates are potential precursors to II-VI materials as they provide access to lower deposition temperatures. Zinc selenide, cadmium sulfide, and cadmium selenide thin films have been deposited from compounds of the type [RM(E2CNEt2)]2 (79, M = Zn, E = S, R = Me 80, M = Cd, E = S, R = Me 81, M = Cd, E = Se, R = Me 82, M = Cd, E = S, R = CH2CMe3 83, M = Cd, E = Se, R = CH2CMe3). The films were superior and higher growth rates were obtained as compared with those... [Pg.23]

Substrates, Films are usually prepared on platinum or gold electrodes which are inert, but semiconducting materials including indium tin oxide, n-type polycrystalline silicon, gallium arsenide, cadmium sulphide and cadmium selenide, graphite [38, 59], and oxide covered metals [60] have also been used. In the majority of cases, the films are produced readily and the only serious limitations are the potential and the nucleophilic nature of the solution. [Pg.40]

The layer-by-layer structure of dithiol SAM and CdS monolayer was confirmed with X-ray photoelectron spectroscopy, Fourier transform infrared reflection-absorption spectroscopy, and inductively coupled plasma mass spectroscopy at each step of composite-film preparation. Photocurrent measurements revealed that the mono-layers of CdS nanoparticles were immobilized without mutual aggregation of particles [36]. Cadmium selenide nanoparticles were prepared electrochemically on gold substrates modified with alkanethio-lated -cyclodextrin SAMs [37]. [Pg.6169]

Cadmium selenide (CdSe) is an n-type semiconductor with a band gap of 1.74 eV at room temperature. The semiconductor nanoparticles with sizes below 100 nm are technologically interesting due to a quantum confinement effect. It has been reported that thin film of CdSe with a band gap of 1.8 eV can be made electrochemically on FTO-coated glass in ChCl/urea ionic liquid containing CdCl2 and 0.1 M Na2S03 (aq.) [24]. Similar to ZnS, the authors presented only a photocurrent spectrum of electrochemically made CdSe. A detailed characterization of CdSe deposits was not shown. [Pg.27]

Apart from metals, good-quality polypyrrole films have also been prepared using a variety of semiconducting materials, such as indium-tin oxide (ITO) glass [39,40], gallium phosphide [41], silicon [42-44], cadmium sulfide, or cadmium selenide [45] as the electrode. [Pg.21]

Cathodic electrodeposition of microcrystalline cadmium-zinc selenide (Cdi i Zn i Se CZS) films has been reported from selenite and selenosulfate baths [125, 126]. When applied for CZS, the typical electrocrystallization process from acidic solutions involves the underpotential reduction of at least one of the metal ion species (the less noble zinc). However, the direct formation of the alloy in this manner is problematic, basically due to a large difference between the redox potentials of and Cd " couples [127]. In solutions containing both zinc and cadmium ions, Cd will deposit preferentially because of its more positive potential, thus leading to free CdSe phase. This is true even if the cations are complexed since the stability constants of cadmium and zinc with various complexants are similar. Notwithstanding, films electrodeposited from typical solutions have been used to study the molar fraction dependence of the CZS band gap energy in the light of photoelectrochemical measurements, along with considerations within the virtual crystal approximation [128].
