In the presence of an activator, naturally, the spectrum, yield, and lifetime are characteristics of the activator molecule. Indeed, the luminescence spectrum of the oxidized ethylbenzene was found to be identical to that of activator fluorescence [221]. 9,10-Dibromanthracene, 9,7-dipropylanthracene, and derivatives of oxazole were used as activators [221,223].
