Abstract The spectral-luminescent properties of europium(III) complexes with p -methylbenzoic acid and nitrogen- and phosphorus-containing neutral ligands of compositions [Eu( p -MBA)_3 · D]_2 · x H_2O and [Eu( p ‑MBA)_3 · 2H_2O]_ n , where p -MBA is the anion of p -methylbenzoic acid and D is 1,10-phenanthroline (phen), 2,2' dipyridyl (dipy), triphenylphosphine oxide (tppo) ( х = 0), hexamethylphosphortriamide (hmpa) ( x = 1), or benzotriazole (bt) ( x = 2) are studied. The electronic absorption spectra, the luminescence excitation spectra, and the Stark structure of ^5 D _0−^7 F _ j (  j = 0–2) electronic transitions in low-temperature luminescence spectra of complex europium(III) p -methylbenzoates are analyzed. It is found that the excitation energy transfer to europium ions occurs from the levels of both p -methylbenzoic acid and neutral ligands.

Nd3+ doped LiLuF4 nanoparticles are explored as photoluminescent nanothermometers and imaging probes. Such host-dopant configuration permits to resolve the fine Stark structure of Nd3+ photoluminescence at 1050 nm, and to use it for subcutaneous temperature sensing.
