The photoluminescence (PL) spectrum was derived from the fluorescence emission by the recombination of free charge carriers, which was useful to represent the separation of photo-generated electron-hole pairs in photocatalyst [23]. The fluorescence intensity was directly proportional to the probability ...
原句 facilitate the separation of photogenerated electron–hole pairs
As a key step in energy conversion, electron-hole pairs generated by light absorption need to be separated and transferred to the surface of the semiconductors1,9,14,15,16,17. Hence, an in-depth understanding of charge separation within semiconductors is desirable for the construction of an ...
aWhen the NaF concentration increased to 1:1.2, the PL intensity of the sample S4 instead increased, inferring that the excess F ions in BiVO4 crystal lattice could act as the recombination centers of photogenerated electron–hole pairs. 当NaF集中增加到1:1.2, S4的改为增加的PL强度样品,推断...
awhich consequently affects the sorption–desorption processes and the separation of the photogenerated electron–hole pairs at the surface of the semiconductor particles. 哪些因而影响吸着解吸附作用过程和分离photogenerated电子孔对在半导体微粒的表面。[translate]...
During photocatalysis, the separation of electron-hole pairs within the semiconductor catalysts, combined with the following energy transfer processes, can readily generate a large amount of highly active species (such as radicals and singlet oxygen1,2,3,4. Notably, these active species could, under...
The trap-to-trap relaxation and recombination dynamics of photogenerated electron/hole pairs in MoS2 nanoclusters have been studied. Static and time-resolved emission experiments have been performed on 3.0 and 4.5 nm diameter nanocluster... R Doolen,R Laitinen,F Parsapour,... - 《Journal of Physi...
