Optically stimulated luminescence (OSL) was studied in rare earth doped SrBPO for the possible applications in radiation dosimetry using optically stimulated luminescence. The study shows that the sensitivity of the Eu doped SrBPO shows good OSL and the sensitivity is comparable to that of AlO:C. It is observed that annealing has a profound effect on the OSL sensitivity. Slowly cooled Eu doped sample shows highest sensitivity and is 77% compared to that AlO:C whereas lowest sensitivity is observed in the quenched sample. Other properties like good linearity and low fading will make this phosphor suitable for the applications in radiation dosimetry using OSL.
对稀土掺杂的SrBPO中的光激发发光（OSL）进行了研究，以探讨其在利用光激发发光进行辐射剂量测定方面的潜在应用。研究表明，掺杂Eu的SrBPO具有良好的OSL灵敏度，且该灵敏度与AlO:C相当。观察到退火对OSL灵敏度有深远影响。缓慢冷却的掺杂Eu样品显示出最高灵敏度，与AlO:C相比为77%，而在淬火样品中观察到最低灵敏度。其他特性如良好的线性和低衰退率将使这种磷光体适用于利用OSL进行辐射剂量测定的应用。
