Abstract

New highly sensitive optically stimulated luminescent phosphors with NaCl moiety and dopants Ca,Cu,P/Mg,Cu,P are developed. These phosphors show very high optically stimulated luminescence (OSL) sensitivity. The dose response for NaCl:Ca,Cu,P is linear up to 1.2 Gy and for NaCl:Mg,Cu,P is slightly sub linear from 0.2 Gy. These phosphors show 30% fading during first 4 and later signal gets stabilised with no further signal loss. These sensitive phosphors will find applications in radiation dosimetry using OSL.

基于NACL的光激发荧光粉的开发用于剂量学的应用

摘要

开发了具有NaCl部分和掺杂剂Ca，Cu，P / Mg，Cu，P的新型高灵敏度光激发发光磷光体。这些荧光粉显示出很高的光学激发发光（OSL）灵敏度。NaCl：Ca，Cu，P的剂量响应在最高至1.2 Gy时呈线性，而NaCl：Mg，Cu，P的剂量响应在0.2 Gy处呈亚线性。这些荧光粉在前4个信号期间显示30％的衰减，随后的信号稳定下来，而没有其他信号损失。这些敏感的荧光粉将在使用OSL的辐射剂量测定中找到应用。
