Abstract

A diagnostic technique based on excited-state complex (exciplex) fluorescence is reported for visualization of diffusion layers formed between mixing liquids. High-spatial-resolution instantaneous images and time-sequenced images are presented. Single drops and jets are visualized mixing in a liquid pool. Time-resolved images of exciplex fluorescence have also been obtained that provide information on the duration of the mixing event and the length and time scales of the diffusion process. The results demonstrate that the technique has the potential to provide new information concerning the physics of liquid mixing processes.
