    • The reproducibility of the tests has been confirmed by several repetitions. A preliminary result shows the behaviour could be concentration independent. We have observed the same behaviour with solutions of RhB in THF of 0.01, 0.015 and 0.025 wt %. Moreover, both the as-prepared solution and the solutions after filtration through a 0.45 μm filter demonstrated similar behaviours. On the other hand, the solvent plays a critical role in the tests. Many other solvents, such as water, chloroform, methanol, methylethylketone and N-N-dimethylacetate, were tested. We did not observe the behaviours of UV-induced changes of RhB PL in these solvents. On the other hand, the response time of PL changes varies from 1 to 10 min in the tests. Nevertheless, at present we have no explanation to the results. The UV-induced RhB aggregation and changes in PL behaviour is worth further studies.
