Controlled fabrication of nanostructured ZnO particles and porous thin films via a modified chemical bath deposition method

Photovoltaic Properties of Aluminum Doped Zinc Oxide Electrodes Based on Variation of Aluminum Impurities in the Semiconductor

“…The deposition time was varied between 2 and 5 h (Figure 2). It was observed that at the initial stage of the deposition process, the film growth rate was rapid, showing an increase rate of about 0.21-0.28 nm/min however, after 4 h, the growth rate became slower until final thickness was obtained at 5 h. This could be ascribed to decrease in number of free metal and chalcogenide ions in the solution [22,24]. Measured values of the film thickness and surface roughness are presented in Table 1.…”

Structural and substructural features of chemically deposited zinc oxide thin films

“…Most of these processes are characterized by high complexity, and they necessitate use of high vacuum, energy or temperature during synthesis. Nowadays, chemical bath deposition (CBD) [10][11][12][13][14][15] is one of the most promising methods for obtaining ZnO films. Its main advantages are simplicity and efficiency, requiring only low temperature and pressure during synthesis, and, also affording the possibility of obtaining of large-areal layers on substrates of different shapes.…”

“…[10,[12][13][14] To generate ZnO layers, we employ different chemical reagents as precursors. Other researchers [10][11][12][13] have obtained zinc-oxide films from solutions of zinc nitrate and hexamethylenetetramine (HMTA) [10][11], hexamethylenetetramine and ammonia [12], and ethylenediamine and trietanolamine [13]. In contrast, in making the films, we employed a more accessible solution of zinc sulphate (ZnSO 4 ), thiourea (CS(NH 2 ) 2 ) and ammonia (NH 4 OH), the latter serving as a complex agent to control sedimentation.…”

Synthesis of Liquefied Petroleum Gas (LPG) Sensor based on Nanostructure Zinc Oxide using Chemical Bath Deposition (CBD) Methods

“…al., 2008) CBD is a simpler method and less expensive than its predecessor with some methods such as Chemical Vapor Deposition (CVD), one-step soft solution, spray pyrolisis, and anodization. CBD method is done by simply immersing the substrate into a solution of "aqueous metal salt" which are controlled by temperature condition, pH and duration of immersion (Wang and Xie, 2006).…”

“…This is due to ZnO is n-type semiconductor which has some very good electrical properties for use as sensors, such as having a high mobility of conduction electrons, is stable to chemical treatment and heat treatment, conductivity varies with the concentration of adsorbed gases and contains no toxins (Wu, et. al., 2008;Wang and Xie, 2006) …”
