Fabrication and Characterization of Spin-coated TiO2 Films

Abstract

Porous TiO 2 films were deposited on glass and ITO coated glass substrates by spin coating for spinning rates of 2000, 5000, 2000 followed by successive run of 5000 rpm (2000-5000). The AFM, SEM, XRD and UV-Vis analysis of the films coated on bare glass substrates for individual and 2000-5000 rpm runs showed amorphous and crystalline behaviours respectively, while TiO 2 films deposited on ITO/Glass substrates show crystalline structure. Both substrate nature and thickness of the films influence the formation of the crystallinity of the films. Also AFM images reveal that the roughness values of the films are independent of substrate.

Water–alcohol–TiO2 dispersions as sustainable ink

“…[16][17][18] The solutionbased methods used to obtain TiO 2 nanoparticles include hydrothermal, solvothermal, hydrolytic and non-hydrolytic sol-gel syntheses. 16,19,20 The functional TiO 2 layers are usually obtained through various coating and printing methods such as dip coating, 21,22 spin coating, 23,24 drop casting, 25,26 screen printing, [27][28][29] inkjet printing, 14,15,30 3D-printing, 31 and various contact printing techniques (gravure, offset, flexography, etc.). [32][33][34] All of the coating and printing deposition methods require the rheological adjustment of a functional ink to meet the specific technological conditions and to control the thickness of the depositing layer.…”

Study of Structural, Optical, Morphology and Photoelectrochemical Properties of Melanin Sensitized TiO2 Thin Films Prepared by Chemical Bath Deposition Method

“…The material has been synthesized using various methods. These includes chemical bath deposition (CBD), [16] chemical vapor deposition (CVD), [17] hydrothermal, [18] spin coating, [19] pulsed-DC magnetron sputtering, [20] dip coating, [21] sol-gel, [22] spray pyrolysis, [23] successive ionic layer adsorption and reaction method (SILAR). [24] Among these, CBD is an effective method to prepare TiO2 films at low temperatures.…”

Influence of deposition temperature on the optical, structural, morphological, compositional and photoelectrochemical properties of TiO2 thin films

“…Some of them are solvothermal [7], sol-gel [8], microwave assisted [9], electro spinning [10], hydrothermal [11] etc. Among all these synthesis techniques, hydrothermal method offers a promising approach for TiO 2 synthesis.…”
