Time-Dependent Photoluminescence of Nanostructured Anatase TiO2 …
网页2019年10月11日 · We show that the PL spectrum of commonly used nanostructured anatase TiO 2 thin films in aqueous media is time-dependent, with pH-dependent broadening at the low energy side of the spectrum in time. By global analysis of the spectrotemporal PL behavior and the effect of addition of NaCl at neutral and mildly acidic conditions, we show that this ...
