Tuning Fluorescence in Dye-Clay Nanocomposites

Original language description

Intercalation and surface modification of layer silicates (phyllosilicates) offers the way to nanomaterials with new functionalities and with a wide scale of practical applications. Present work summarizes the results of fluorescence study obtained for series of intercalates, where the dye guests were: rhodamine B, methylene blue and methyl red. As a host matrix we used: three types of montmorillonite with different total layer charge and vermiculite. Results showed that the ordering of guest moleculesand fluorescence wavelength range is affected by series of factors like: layer charge, charge distribution on the silicate layer, the way of sample preparation, the size and shape of the dye guest molecule and their interaction ability. The shape and position of fluorescence emission band is a result of cooperation of all these factors, where the key role plays the layer charge on the tetrahedral sheet in silicate layers.
