Some Aspects of Ozone Induced Chemiluminescence of Xanthene Dyes

Hot electron-induced electrochemiluminescence of fluorescein in aqueous solution

“…(14) cannot be the source of emission. Pruetz et al [28] assumed both the excitation steps (12) and (13) possible at first, but later Pruetz and Land [29] turned to the opinion that ox-red pathway composed by reaction (11) and (13) was the actual RCL pathway. This was supported by Rodde and Grossweiner [50], who mainly studied a somewhat different system in which they first produced optically excited dyes by a flash of light before giving the electron pulse.…”

“…Fluorescein is known to emit similar chemiluminescence emission spectrum to that of its fluorescence emission during treatment with ozone in ethanol and methanol [11] and in terbutanol [12]. This CL is known to consume both fluorescein and ozone.…”
