Here we show that the praseodymium N,N-dimethylaminodiboranate complex Pr(H₃BNMe₂BH₃)₃ and the 2,2,6,6-tetramethylheptane-3,5-dionate complex Pr(thd)₃ can serve as volatile carriers for ²²⁵Ac. The actinium coordination complexes Ac(H₃BNMe₂BH₃)₃ and Ac(thd)₃ are the likely species subliming with the carrier material. A sample of ²²⁵Ac-doped Pr(H₃BNMe₂BH₃)₃ was used to deposit amorphous ²²⁵Ac-doped praseodymium boride films on glass and Si(100) at 300 °C. Furthermore, 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.
