摘要
An analytical form of concentration dependence of photo- and X-ray luminescence intensity in liquid phosphors is presented in this paper. Theoretically obtained dependences were compared with experimental results that were obtained for 3-Hydroxyflavone in toluene and acetonitrile solutions. The value of density of electronic excitations occurring in liquid phosphor after the absorption of X-rays was estimated. The results show that the solution of 3-Hydroxyflavone in toluene is not only an effective photo-luminophore but also an efficient X-ray luminophore, which make it possible to choose the optimal concentration of impurity molecules in order to obtain maximal scintillation impulse in practical applications of liquid scintillators.
