Lead tin fluorophosphates (PTFP) glass doped with organic dye stilbene 420 is prepared. The melting temperature of the doped glass is below 250℃and the characteristic temperature is about 75℃. The luminescence excited by 60Co 1.25MeV gamma ray is measuredand is compared with organic scintillator ST401 with the same thickness. The scintillation of doped PTFP glass is from 1 to 2 percent that of ST401.
