Nanostructural Growth Investigation of ZnO Nanorods Derived from Chemical Bath Deposition for Transparent Heater Application

Effect of growth time on Ti-doped ZnO nanorods prepared by low-temperature chemical bath deposition

Ti-doped ZnO nanorod arrays were grown onto Si substrate using chemical bath deposition (CBD) method at 93 °C. To investigate the effect of time deposition on the morphological, and structural properties, four Ti-doped ZnO samples were prepared at various deposition periods of time (2, 3.5, 5, and 6.5 h). FESEM images displayed high-quality and uniform nanorods with a mean length strongly depen...

Photoluminescence transient study of surface defects in ZnO nanorods grown by chemical bath deposition

Investigation of chemical bath deposition of ZnO thin films using six different complexing agents

Chemical bath deposition of ZnO thin films using six different complexing agents, namely ammonia, hydrazine, ethanolamine, methylamine, triethanolamine and dimethylamine, is investigated. As-grown films were mainly ZnO2 with a band gap around 4.3 eV. Films annealed at 400 ◦C were identified as ZnO with a band gap around 3.3 eV. X-ray diffraction and micro-Raman spectroscopy revealed that as-gro...

Effect of growth time on ZnO thin films prepared by low temperature chemical bath deposition on PS substrate

ZnO thin films were successfully synthesized on a porous silicon (PS) substrate by chemical bathdeposition method. X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM),and photoluminescence (PL) analyses were carried out to investigate the effect of growth duration(3, 4, 5, and 6 h) on the optical and structural properties of the aligned ZnO nanorods. T...

Size-controlled growth of well-aligned ZnO nanorod arrays with two-step chemical bath deposition method

Well-aligned ZnO nanorod arrays (ZNAs) with different sizes in diameter were fabricated on Si substrates by two-step chemical bath deposition method (CBD), i.e. substrate pretreatment with spin coating to form ZnO nanoparticles layer and CBD growth. The effects of substrate pretreatments, pH, angel (θ) between substrate and beaker bottom and growth time (t) on the structure of ZNAs were investi...
