Analysis of gleaming defects obtained for various LMW fluorescent probes in 5CB.

(a) Fluorescent intensity profiles averaged over N = 40 gleaming defects, obtained for different probes; NPB (0.02 wt%), PL (0.1 wt%), QT (0.1 wt%), C504T (0.1 wt%), C545T (0.1 wt%), BPZ (0.02 wt%), and BTBP (0.1 wt%). Each fluorescence profile was normalized by intensity obtained at a distance of ~3 μm from the peak. The error for each data point was approximately ±5~7% (N = 40), which was not shown in the plot for visibility. (b) The averaged peak values (N = 40) were plotted with respect to the molar molecular volume in their solid states, suggesting a positive correlation between them. The data include the values obtained for two different concentrations indicated by ‘low’ and ‘hi’; NPB (0.01, 0.02 wt%), PL (0.01, 0.1 wt%), QT (0.01, 0.1 wt%), C504T (0.01, 0.1 wt%), C545T (0.01, 0.1 wt%), BPZ (0.01, 0.02 wt%), and BTBP (0.01, 0.1 wt%).
