摘要
制备了掺杂有机染料芪420的铅锡氟磷酸盐杂化闪烁玻璃(lead tin fluorophosphates,简记为PTFP),测量其玻璃转变温度为75℃,染料在玻璃中的荧光发射峰位为446nm.测量了几种掺杂浓度的闪烁玻璃在60Co源1.25MeV伽马射线激发下的发光,并和同样厚度的有机闪烁体ST401的发光进行比较,约为ST401发光的1%—2%.
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 ^ 60 Co 1.25？MeV gamma ray is measured,and 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.
