AI Article Synopsis
- Pure, TiO2-doped, and TiO2/Ag-doped WO3 films were created using evaporation techniques.
- The electrochromic properties of these films were analyzed using Raman spectroscopy and chronoamperometry.
- There is a negative correlation between the intensity of a specific Raman peak (at 810 cm(-1)) and the coloration efficiency, indicating that higher peak intensity leads to lower efficiency in color change.
Article Abstract
Pure, TiO2-doped and TiO2/Ag-doped WO3 films were prepared by evaporation and electron beam evaporating. Raman spectroscopy and chronoamperometry were used to characterize the electrochromic properties of the samples. The correlation between the relative intensity of the Raman peaks, corresponding to the Raman sharp peak of the crystalline phase at 810 cm(-1) is negative, that is to say the higher the relative intensity of the Raman peaks, the smaller the coloration efficiency.

With the increasing demand for food safety monitoring, the development of efficient, convenient, and green gas sensors has become a current research hotspot. Triboelectric nanogenerator (TENG) as a triethylamine sensor is a cutting-edge strategy for detection without the need for an additional power source. In this study, synthesized WO/MXene materials were prepared and bilayer thin films of carbon quantum dots (CPDs)-WO/MXene TENG.

Atomic-layer-deposited (ALD) "leaky" TiO has gained interest as a charge-selective protection layer for semiconductor solar fuel electrodes. Here, the use of sputter-deposited TiO layers as hole-selective contacts for WO/CuWO type-2 heterojunction water oxidation photoanodes is demonstrated for the first time. TiO protection layers with varying thicknesses (2 to 128 nm) were deposited by using the radio frequency (RF) magnetron sputtering technique.

Thin films based on tungsten oxide (WO) were grown by nanosecond pulsed laser deposition on alumina printed-circuit boards to fabricate electrochemical sensors for nitrogen dioxide (NO) detection. Samples exposed to thermal annealing (400 °C for 3 h) were also produced to compare the main properties and the sensor performance. Before gas testing, the morphology and structural properties were investigated.
