The installation of a massive liquid scintillator detector, Borexino, devoted to the real time detection of low energy solar neutrinos, has been recently proposed at the Laboratory of Gran Sasso. The key features of this next generation solar neutrino experiment crucially rely upon the properties of the liquid scintillator used as detection medium. Thus a careful evaluation of these properties has been carried out. In particular we describe here the results of the measurements performed to determine the decay time of the scintillation light pulse for alpha and electron excitation in different solvents and solutes suitable to be used in the detector.
