  The phenomenon of aging in soft matter systems is an intriguing and
interesting. In his study we investigate the microstructure and aging dynamics
of fluorescent nanoclay gels formed from the mixture of small (~25) and large
(~250) aspect ratio nanodiscs using various experimental techniques. We examine
how the presence of one kind of clay in other clay of different nature affect
the aging dynamics, microstructure and the final resulting phase. Viscosity of
the dispersions grows as a power-law with waiting time of the system and the
dispersions initially show Maxwellian behaviour but deviated as the time
progressed. Fractal dimension, df of the gels is found to be 2.5. Confocal
micrographs revealed clear grain boundaries in the nanoclay gels, since
Na-Montmorillonite exhibit fluorescence. We also report for the first time that
the gels containing sodium MMT gives a bright green-yellow fluorescence in
ultra violet light. These fluorescent gels may be useful in industry and
academic research.
