Preparation of Hemicyanine Dye Encapsulated Silica Particles and Their Application in Cotton Fabrics
Trans-4-p-(N, N-D1e (2-hydroxyethyl)) styryl-N-ethyl pyridinium bromide (DHEASPBr-C2), a hemicyanine fluorescent dye, was encapsulated into silica nanoparticles by co-hydrolysis and co-condensation of organosilanes in the presence of the dye.The dye containing silica nanoparticles were applied onto cotton fabrics.Scanning electron microscopy (SEM), UV-vis spectra, single-photon emission fluorescence spectra and reflectance spectra of the samples were characterized.The SEM results showed that the particle size (ranging from 100-200 nm) and dye encapsulating (1.5-8.1 mg dye per g silica matrix) could be adjusted by the concentration of fluorescent dye and organosilanes.The reflectance of the treated cotton fabrics showed that there were obvious adsorption spectra in 410-540 nm and emission spectra in 560-700 nm.
