Scintillating glass doped with organic activator p-TP and/or POPOP

Abstract

Two organic activators, p-TP(p-terphenyl) and POPOP (1,4-bis(5-phenyloxazol-2-yl) benzene), which are normally used to prepare the scintillating plastic, were doped in tin fluorephosphate glasses to develop a serial of scintillating glasses with different concentrations. The fluorescence spectra and the transmission spectra of some scintillating glass were explored and the actual concentration organic in scintillating glass was estimated by comparing the extracted solution from glass with standard solution. Results show that the organic materials can be doped into inorganic glass, however, the actual concentration of organics doped in the glass is very low. Compared with scintillating plastic, the emission peak of scintillating glasses move towards the longer wavelength and POPOP is not wavelength shift any more.
