“…LuPO 4 is long known and a well‐established chemical compound that has a high‐density (6.53 g cm −3 ) as well as a wide band gap (8.85 eV), thus large enough to allow UV‐C emission . The clinical efficacy of several 177 Lu radiopharmaceuticals has been demonstrated, and it is expected that they will be commercially available in the near future …”

Pr3+‐doped LuPO4 emits UV radiation between 225 and 280 nm, where DNA shows strong absorption bands. Therefore, a systematic study of the luminescence of Pr3+ doped LuPO4 is performed: Different doping concentrations, particles sizes, and excitation schemes (vacuum UV at 160 nm and X‐rays 50 kV, 2 mA, tungsten target) are compared. The emission spectra in the UV range depends on the excitation energy and the particle size. Microcrystalline particles (6 µm) comprising 1% Pr3+ display the highest emission intensity at 234 nm upon vacuum UV as well as X‐ray excitation. Sub‐microscale particles (20–50 nm) of LuPO4:Pr3+ (1%) show the same UV emission under X‐ray excitation as the larger particles but do not emit under vacuum UV excitation. Colloidal nanoscale particles (5 nm) do not show emission in the UV‐C range. Based on the high‐density and strong X‐ray absorption of LuPO4, the implementation of Pr3+ doped LuPO4 particles of suitable size (20–50 nm) could improve the well‐established radiation therapy. Owing to the strong absorption and low penetration depth of UV‐C radiation in biological tissue, Pr3+‐doped LuPO4 particles located directly in cancerous tumors could allow for additional treatment with cell‐damaging UV‐C radiation.

“…Т = 300 K The structure of the excitation luminescence spectra of praseodymium ions in larger LuPO 4 -Pr nanoparticles (Fig. 6, curve 1) is identical with that for the single crystal LuPO 4 -Pr [14]. The structure of intracenter absorption bands is changed with the decrease of nanoparticle sizes.…”
