我们研究了 Nd 掺杂 LiCaAlF6 单晶的辐射发光和热致发光 (TL) 性质。样品显示出源自 Nd3+ 离子的 5d-4f 和 4f-4f 跃迁的放射发光峰。 Nd 掺杂 LiCaAlF6 单晶的发光可以用在 VUV 到可见光范围内具有灵敏度的光电探测器来检测。 TL 强度作为 X 射线剂量的函数从 100mGy 单调增加到 10Gy。掺Nd LiCaAlF6单晶在高剂量剂量测定应用中具有优势。
We have investigated radioluminescence and thermoluminescence (TL) properties of the Nd-doped LiCaAlF6single crystal. The sample showed the radioluminescence peaks originating from both the 5d-4f and 4f-4f transitions of the Nd3+ion. The luminescence of Nd-doped LiCaAlF6single crystal is detectable with the photodetectors having a sensitivity in the wavelength from the VUV to visible range. The TL intensity monotonically increased as a function of X-ray dose from 100 mGy to 10 Gy. The Nd-doped LiCaAlF6single crystal has an advantage in high-dose dosimetry applications.
