| Summary: | © 2017 Elsevier B.V. The isostructural [Ln(L) 0.5 (NO 2 -BDC)(H 2 O)]·3H 2 O complexes (Ln = Eu III (I), Tb III (II), Gd III (III) and 0.012Eu III /0.494Tb III /0.494Gd III (IV); L = BDC 2− or BDC 2− /NO 2 -BDC 2− ; H 2 BDC = 1,4-benzenedicarboxylic acid) were synthesized and characterized by powder X-ray diffraction and wavelength dispersive X-ray fluorescence. Room temperature and temperature dependent photoluminescence behavior of the title complexes were studied in solid state using the ground crystals. The rare constant intensity of Eu III with increasing temperatures in complex I is reported, and a potential of the mixed complex IV as a ratiometric luminescence thermometer in a temperature range 333(2)–423(2) K is illustrated. |
