Synthesis, Characterizations, and Optical Properties of Stacked Porous Thin Films Derived from Sol–Gel Process

An active core fiber optic sensor for detecting trace H2S at high temperature using a cadmium oxide doped porous silica optical fiber as a transducer

“…It was found that the pore size in the newly cut end of the sol-gel silica fiber is smaller than the resolution of the electron microscope (2.5 nm). This result agrees with the reported microstructure of sol-gel silica thin films [23,24]. The pore size of a pure sol-gel silica film was reported to be in the range of 1-3 nm.…”

Effect of Thickness on Photocatalytic Activity of TiO2 Thin Films

“…Titanium dioxide is a semiconductor material having a large number of applications such as solar energy conversion [1], photocatalysts [2], gas sensor [3], photochromic devices [4], optoelectronics [5], and ceramic membrane [6]. This is mainly due to its favorable properties like non-toxicity, chemical inertness, and stability over a wide pH range under irradiation conditions.…”

Crystallization behavior of Li+-doped SiO2–TiO2 films prepared by sol–gel dip coating

“…Solgel method can be used to fabricate almost any single-or multi-component oxide films [2]. TiO 2 thin films have been widely investigated for various optical applications [3] and have attracted considerable attention for optical filter [4], gas sensor [5], ceramic membrane [6], and photocatalyst [7]. Mixed silica-titania compositions are also of significant technological importance.…”
