Figure 2.

PL spectra from Z^c(l) with respect to time evaluated at λ_ex = 275 nm. The first measurement was achieved as reference by only measuring the PL emission from Z^c(l) prepared as in section 2.2.1. After 1 minute 1 mL of water, in this case, was added to later measure spectra at every time showed in this figure. Each peak was identified with a red number at the top of figure, corresponding to description in this section.
