Figure 10. Effect of rotation speed and water fraction on the FL of
solutions of TPE particles (a) change in the FL maxima at different
rotation speeds and constant water fractions. Change in the relative FL
maxima as a function of rotation speed at (b) 50% and (c) 95% water
fraction. (d) Change in relative intensity of FL as a function of water
fraction at constant rotation speeds. Effect of the rotation speed of
the VFD tube on the size of the TPE particles. (e) Reduction of particle
size by increasing rotational speed with the water fraction at 80%. (f)
Relationship between TPE particle size and rotation speed at different
water fractions (Inset: Distribution of TPE particles prepared at 0 and
3000 rpm rotation speeds). (g) The fluorescence quantum yield (%) was
measured for VFD-mediated (red line) and conventional batch (dotted
line) methods at different water fractions57. (h) The
effect of rotation speed on the relative intensity of AIE-HBP (1 mM) and
(i) and (j) size distribution and schematic drawing of AIE-HBP particles
(1) before and (2) after VFD58. (a-g) Reproduced with
