Visible-light induced superhydrophilicity on a WO(3)/ITO/CaFe(2)O(4) heterojunction thin film

Abstract:
The WO(3)/ITO/CaFe(2)O(4) film surface showed visible-light induced superhydrophilicity, which is ascribed to efficient charge separation, resulting from the recombination of photo-electrons from WO(3) with photo-holes from CaFe(2)O(4) in the ITO layer.

Photoluminescence: Applications
Photoluminescence offers a wide range of applications due to its inherent sensitivity and selectivity. This technique allows for both direct and indirect analyses of the analyte. Direct quantitative analysis is possible when the analyte exhibits a favorable quantum yield for fluorescence or phosphorescence. However, an indirect analysis may be feasible if the analyte is not fluorescent or phosphorescent, or if the quantum yield is unfavorable. Indirect methods include reacting the analyte with...
Photoelectric Effect
When light of a particular wavelength strikes a metal surface, electrons are emitted. This is called the photoelectric effect. The minimum frequency of light that can cause such emission of electrons is called the threshold frequency, which is specific to the metal. Light with a frequency lower than the threshold frequency, even if it is of high intensity, cannot initiate the emission of electrons. However, when the frequency is higher than the threshold value, the number of electrons ejected...
