Abstract

We have synthesized Dy-doped LiCaPO₄ samples by the conventional solid-state reaction and evaluated photoluminescence (PL), scintillation, and dosimetric properties. The samples showed luminescence which was attributed to the 4f-4f transitions of Dy³⁺ by irradiation of UV and X-ray. The highest PL quantum yield (QY) of 59.2% was obtained from the 0.5% Dy-doped sample. The 0.5% Dy-doped sample exhibit the highest intensity in scintillation and thermally stimulated luminescence (TSL) as well. In TSL dose response function, the 0.5% Dy-doped LiCaPO₄ showed the proportional relationship from 0.01 to 30 mGy under X-ray irradiation. The TSL intensity surpassed the commercial product.

镝掺杂LiCaPO4的剂量学性质

我们通过传统的固相反应合成了镝掺杂的LiCaPO4样品，并评估了其光致发光(PL)、闪烁和剂量学性质。在紫外和x射线的照射下，样品显示出由Dy3+的4f-4f跃迁引起的发光。掺杂0.5%的样品得到了最高的PL量子产率(QY) 59.2%。掺量为0.5%的样品在闪烁和热激发发光(TSL)方面表现出最高的强度。在TSL剂量响应函数中，0.5% dy掺杂的LiCaPO4在x射线照射下呈现0.01 ~ 30 mGy的比例关系。TSL强度超过了商业产品。
