Effect of the U.V. Irradiation on the Aqueous Solution of Dye (i.e. Cresol Purple)
Abstract: This study aimed to estimate the effect of the U.V. irradiation on the aqueous solution of cresol purple. Then study the effect of the activation energy of each electron transfere on the absorbance and λmax values. The absorbance and λmax values of the selective λmax solutions were chanced in most solutions, where the U.V radiation gave different values at different irradiation periods, most of solution gave low values of absorbance …

Size Dependent Fluorescence Decay Dynamics of MoS2 Nanoflakes
Abstract: This paper reports a profound method to prepare MoS2, and the effect of ultraviolet light irradiation on its emission characteristics. The exfoliation of molybdenum di-sulfide (MoS2) in a liquid phase has been achieved successfully via probe sonication for different time intervals followed by centrifugation method. Ultraviolet–visible (UV–vis) spectra of the obtained MoS2 dispersions at different exfoliation time indicate that the concentration of MoS2 nanosheets as well as MoS2 quantum dots …
