Spectroscopic peculiarities of CsCaI3:Tm2+ single crystals examined through one-photon and excited state excitation spectroscopy

The CsCaI3 single crystals doped with Tm2+ were grown by Bridgman technique. Divalent thulium luminescence related to the 4f13-4f13 intra-configurational and 4f125d1-4f13 inter-configurational transitions were analyzed as a function of temperature. Excited state excitation spectroscopy has been applied within a wide spectral range to examine peculiarities of transitions between different 4f125d1 excited states of Tm2+. This two-color excitation experiment was useful to assess d-d photon-absorption processes that are relevant to observed up-conversion phenomena attributed to effective anti-Stokes green luminescence around 550 nm. Furthermore, activation energy of 4f125d1 → 4f13 luminescence quenching was estimated and high value of 2F5/2 → 2F7/2 emission cross-section was determined in CsCaI3:Tm2+. Our spectroscopic study was performed to complement and verify the previous investigation in this field.

Reduction of azobenzene by neodymium(II), dysprosium(II), and thulium(II) diiodides

The diiodides of divalent neodymium (1), dysprosium (2), and thulium (3) LnI2 readily reduce azobenzene under ambient conditions to give binuclear complexes [LnI(THF)2]2(N2Ph2) 2 (Ln=Nd (4)
