The time-dependent changes in the electronic absorption spectra (UV-vis) of some ferrocene derivatives in the halocarbon solvents chloroform and carbontetrachloride have been investigated after removal of the photoexcitation by monochromatic radiation (UV) in nitrogen atmosphere. The spectral responses with time after removal of photoexcitations are(More)
The time-dependent changes in absorbance in the case of ferrocene-doped poly(methyl methacrylate) thin films containing chloroform molecules have been investigated after photoexcitation in nitrogen atmosphere. Photoexcitations have been made by the monochromatic light (using Xe-source and a monochromator) in the UV range. An increase in absorbance(More)
The changes in the electronic absorption spectra (UV-Vis) (after photoexcitation) of poly(methyl methacrylate) (PMMA) thin films doped with a metallocene and containing chloroform molecules as impurities, have been studied as a function of photoexcitation wavelength (210-750 nm), photoexcitation time (duration), amount of metallocene in the film and amount(More)
