The laser-induced phase separation of charcoal particles on additive-free cotton linters cellulose paper was investigated by electron and optical microscopy, colorimetry, and diffuse reflectance FT-IR. The fibre bundles were vaporised in depth of several 10 μm above destruction fluence thresholds using visible 532 nm radiation. This is in contrast to mid-ultraviolet 213 nm radiation, where only the...
Spectroscopic characteristics, i.e. absorption, fluorescence, fluorescence excitation spectra, fluorescence decay time, fluorescence polarization degree of novel silicon-containing organic polymers including main chain anthracene groups were investigated. Three kinds of emission spectra were revealed and assigned to polaron-exciton, anthracene and anthracene dimer. The measured fluorescence polarization...
In this paper spectroscopic characteristics of two new carbosilane polymers 1 and 2 containing anthracene and acetylene units in their main chain is discussed. To investigate excitation energy migration along the polymeric chain we have measured the fluorescence polarization characteristics
