Here we show that the praseodymium ,-dimethylaminodiboranate complex Pr(HBNMeBH) and the 2,2,6,6-tetramethylheptane-3,5-dionate complex Pr(thd) can serve as volatile carriers for Ac. The actinium coordination complexes Ac(HBNMeBH) and Ac(thd) are the likely species subliming with the carrier material. A sample of Ac-doped Pr(HBNMeBH) was used to deposit amorphous Ac-doped praseodymium boride films on glass and Si(100) at 300 °C. The α emission spectra of the refractory films are well-resolved, suggesting that they could be used as radioactive implants for brachytherapy and related treatments.
在此我们表明，镨的二甲基氨基二硼酸盐配合物Pr(HBNMeBH)和2,2,6,6-四甲基庚烷-3,5-二酮配合物Pr(thd)可作为锕的挥发性载体。锕配位配合物Ac(HBNMeBH)和Ac(thd)可能是与载体材料一起升华的物种。使用掺锕的Pr(HBNMeBH)样品在300°C下在玻璃和Si(100)上沉积非晶态掺锕硼化镨薄膜。难熔薄膜的α发射光谱分辨率良好，表明它们可用作近距离放射治疗及相关治疗的放射性植入物。
